Journal of Cellular Biotechnology is a peer-reviewed international journal for advancing research activities in the field of cellular biotechnology. It serves as a medium for the publication of full papers, invited reviews, short communications, technical notes and letters to the Editor-in-Chief on all aspects of cellular biotechnology. This comprises molecular biological topics covering biochemical, chemical, pharmacological or bioprocess engineering aspects, as well as the development of novel biomaterials. Therefore, cellular biotechnology differs from biology, biochemistry, and other basic life sciences by its emphasis on using the knowledge of bioscience to solve important practical problems. Papers presenting information of a multidisciplinary nature - not suitable for publication in a journal devoted to a single discipline - are particularly welcome.
Manuscripts submitted for the
Journal of Cellular Biotechnology are expected to cover activities related to molecular diagnostics, the expansion of human primary cells for individualized therapies or drug testing, 2- and 3-dimensional co-culture techniques, cell line validation, tissue engineering, and stem cell biology for the treatment of human pathologies. This includes studies on the design of reactors and research on cellular biology and physiology of mammalian cells in vitro and in vivo, and tissue. Of special interest is the rational manipulation of reactions through metabolic engineering techniques or specific reactor operations that lead to biomaterials with unique properties. Also, biochemical and physiological studies of metabolism and enzymes as relevant for tissue culture cells, investigations at the molecular level including transcription/translation control; design and engineering of products by molecular strategies; engineering of cellular modification and transport systems such as post-translational protein modifications as well as protein and metabolite secretion; molecular strategies of screening for new or modified products (e.g. pharmaceuticals or bioactive compounds). In addition, investigations in preclinical animal experiments are welcome.
The endeavour of the Editor-in-Chief and publisher of the
Journal of Cellular Biotechnology is to bring together contributions from those working in various fields related to cell-cell or cell-material interactions all over the world. The editorial board members of the
Journal of Cellular Biotechnology are from those countries in Europe, Asia, Australia and America where appreciable work in cellular biotechnology is being carried out. Each editor takes responsibility to decide on the acceptance of a manuscript. He/she is required to have the manuscript appraised by two referees and may be one of them himself. The executive editorial office, to which the manuscripts have been submitted, is responsible for rapid handling of the reviewing process.
Abstract: BACKGROUND: It is now known regulatory effect of gaseous mediators in many bodily functions. These mediators include nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2 S). However, detailed data on the regulatory role of each of these gasotransmitters (GTs) are still not sufficiently studied. OBJECTIVE: The aim of this study was to investigate on models of microrheological behaviour of intact red blood cells and their recovered ghosts of cellular responses to all three known gasotransmitters: NO, H2 S, and CO. METHODS: In experiments with intact red blood cells (RBCs) and their recovered ghosts (filled…with an isotonic solution of known viscosity), deformability (RBCD) and aggregation (RBCA) were recorded after incubation of cells with GT donors or stimulators of their endogenous synthesis. RESULTS: It was found that all three GT donors moderately increased the deformability of both intact RBCs and their recovered ghosts (by 5–10%, p < 0.05). In addition GT donors and substrates of their endogenous synthesis significantly reduced RBCA, from 20 to 37% (p < 0.01). Experiments with inhibition of soluble guanylate cyclase (s-GC) almost completely eliminated the RBCD increasing effect of GT donors CONCLUSION: In present study it was demonstrated that all three known gaseous mediators: NO, CO and H2 S cause moderate statistically significant positive alterations in RBC deformability as well as a noticeable decrease in RBC aggregation. This was confirmed both in experiments with gasotransmitter donors and stimulators of GT endogenous synthesis. In addition, the data obtained suggest that RBC microrheological responses to the actions of all three GTs are associated with activation of the guanylate cyclase signalling cascade.
Abstract: Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) has caused more than 18 million confirmed cases and 700000 deaths worldwide after the outbreak in November 2019 (COVID-19). It has been considered as most pathogenic infection under this category. Till date none of the therapeutics or prophylaxis measures have been claimed by any researcher which could cure the patient suffering from the SARS-CoV-2 infection. There is an urgent need for any alternative and effective way of disease management for COVID-19. However, convalescent plasma therapy (CPT) has gain attention of researchers with significant improvement of patient survival rate. Interestingly, there are numerous examples where…CPT has proven its potential upon post-exposure prophylaxis and/or treatment in various diseases including COVID-19. This review summarizes the essential elements related to CPT, its past clinical evidences and application of CPT for the management of SARS-CoV-2 infection during COVID-19. We used the published literatures from PubMed, EMBASE and Medline databases until 31st May 2020.
Abstract: INTRODUCTION: Novel concept known as tissue engineering is for the betterment of human. The use of much advanced molecular science and cell biology in processing the tissues to regenerate even after the loss of inborn tendency of pluripotent cells to multiply is possible by this new therapy. CONTENT: Periodontal tissue regeneration in both height and function is attributed to a complete recovery of the periodontal structures, that is, the formation of alveolar bone, a new connective attachment through collagen fibers as well as functionally oriented on the newly formed cementum is regeneration. Cell based therapies including tissue regeneration…is an alternative approach for the regeneration of tissues damaged by disease or trauma. SUMMARY: Though tissue engineering requires the fundamentals of all the three keys namely genomics, proteomics and biometrics to give the solutions to biological problems appearing in dentistry as well as medical sciences.
Abstract: BACKGROUND: There are certain issues using saliva as a sample for steroid hormone analysis in clinical diagnostics. Therefore, it is important to test whether currently available assays are suitable for this approach in a routine laboratory. OBJECTIVES: The analytical performance of two commercially available immunoassays was compared under routine conditions. In addition, salivary steroid hormone levels were compared with serum levels. METHODS: Saliva and serum samples were collected from healthy subjects. Afterwards, the concentration of cortisol, testosterone, progesterone and estradiol in saliva was measured by using the ADIVA Centaur® XP platform and commercially available manual…ELISA kits. Serum levels of the selected steroid hormones were determined by using the ADVIA Centaur® platform. RESULTS: Currently, the ADVIA Centaur® XP platform cannot be used for the quantification of steroid hormones in saliva due to an insufficient calibration range. Commercially available ELISA kits on the other side are well suitable for this application. CONCLUSIONS: There are commercially available immunoassays which are sensitive enough for the determination of steroid hormones from saliva and can be used under routine conditions. However, the interpretation of salivary steroid hormone levels stays a challenging task due to the large variability of the results.

Abstract: A vertical flat-type bioreactor consisting of transparent polyethylene (food safe) was constructed, which is characterized by a flexible design and allows the adjustment of a light path of 1 cm – 8.5 cm and a working volume of 1.5 l – 4 l. To characterize the performance of the bioreactor, cultivation experiments were performed with the cyanobacterium Arthrospira platensis (AP) . The growth was assessed continuously by monitoring optical density and intermittently by measuring the dry weight of the AP biomass. An on-line measurement technique for estimating biomass production rate in a photosynthetic microalgae culture was developed. The oxygen produced by…AP in the culture medium was flushed out sparging using a mixture of air and CO2 (1%). Factors which might influence the AP growth were monitored: pH, temperature, oxygen concentration and the filling level were corrected automatically to compensate evaporation losses. As an example, the huge influence of the light intensity on the AP growth was tested. The increase of the photon flux density of 15 to 1200μ mol/(l · d) led to a 22-fold increase of the productivity and a 3.1-fold shorter doubling time. Using an online measurement technique - together with the control of the growth process via a wireless local area network (WLAN) router and virtual private network - allows monitoring the growth of Arthrospira platensis remotely.

Abstract: BACKGROUND: Due to widespread use of pesticides, an individual’s lifetime exposure to pesticide mixtures is unavoidable, resulting in potentiation of toxic effects such as changing metabolic signaling temporarily or permanently due to the formation of free radicals among exposed individuals. OBJECTIVE: This study then looked at the expression of leptin and insulin receptors in Wistar rats exposed to pyrethroid and its effects on adipokines and glycemic indices. METHODS: 84 Wistar rats were randomly selected and divided into two groups. 51 rats were exposed to 1.2 % w/v pyrethroid insecticides, while the remaining 33 rats were grouped…as non-exposed. The groups were divided into three different groups, each with 7, 21, and 41 days. The animals were anesthetically sacrificed and samples of blood were collected after days of exposure. The levels of total antioxidant status (TAS), malondialdehyde (MDA), glutathione (GSH), hydrogen peroxide (H2 O2 ), nitric oxide (NO), glucose and lipids were determined. Blood activities of superoxide dismutase (SOD), glutathione peroxidase (GPX), and catalase (CAT) were also determined. ELISA was used to assess leptin, adiponectin, insulin, CRP, IL-6, and TNFα . Glycaemic indices were calculated appropriately. Leptin and Insulin expression was determined using the reverse transcriptase-polymerase chain reaction (RT-PCR) method. Data obtained were statistically compared, and P ≤0.05 was considered significant. RESULTS: The mean TChol, TAG, and HDL-C were significantly different (p < 0.05) among the exposed groups. The serum mean levels of SOD, GPx, CAT, GSH, TAS, QUICKI, TNFα , IL6, and CRP were significantly reduced (p < 0.05), while mean levels of MDA, H2 O2 , NO, insulin, HOMA-IR, FIRI, leptin, and adiponectin were significantly elevated (p < 0.05) in exposed groups. The relative expression of insulin and leptin genes in exposed and non-exposed groups was also shown by column. CONCLUSION: It is self-evident that pyrethroid chemicals exposure may disrupt carbohydrate and lipid metabolism by raising the risk of obesity among the exposed groups.
Abstract: BACKGROUND: In dogs, an insufficient variety of cell lines commercially available or difficulties in obtaining the existing cell lines developed from various studies results in a limited number of cytotoxicity and related molecular studies integrated with clinical practice. Hence, the doses of many drugs or supportive treatments used in canine tumor cases are adjusted based on studies in humans. OBJECTIVE: A cell line was established from a benign mixed tumor of the canine mammary gland. METHODS: Following surgical removal of the tumor, mechanical dissociation, and PBS washing, a culture process of the tumor cells was performed,…including the passaging, freezing, and thawing stages. After several passages, the morphological characteristics of the cells at the logarithmic growth phase were observed under a phase-contrast microscope. RESULTS: The microscopy of the cells cultured on plastic dishes revealed monolayer colonies. The average passage time, which was 5–6 days in the first three passages, decreased to 2–3 days after the third passage. Microscopic examination of tumor cells revealed an adherent, stellated, and spindle-shaped structure. CONCLUSIONS: No difference was observed in the viability and morphology of the cells thawed even after the long period of freezing (∼18 months). The different canine cell lines can provide promising molecular applications that can be adapted into practical clinics in veterinary science.
