most studies regarding the marrow-derived equine mesenchymal stem cells (mscs) have mainly focusedon the cell transplantation without considering the capacity of differentiation and in vitro requirements of thecells. these concerns were investigated in the present study. equine mscs were isolated from the sternalmarrow aspirates and expanded through two successive subcultures. passage-2 equine ...

We developed a novel thermal spraying technology for a silver-containing hydroxyapatite (Ag-HA) coating with antibacterial activity to reduce the incidence of implant-associated infections. In this study, we determined the concentration of Ag ions that show antibacterial activity in fetal bovine serum (FBS) and antibacterial activity of the Ag-HA coating in FBS. The minimum inhibitory concentra...

Background and Objectives The imperative role of dental pulp stem cells (DPSCs) in regenerative therapy demands an in-vitro expansion which must deal with the safety and ethical problems associated with fetal bovine serum (FBS). The primary aim of this study was to compare the effects of human platelet rich fibrin (hPRF) exudate Vs FBS on proliferation and osteodifferentiation of human dental p...

The apicomplexan parasite Cryptosporidium causes cryptosporidiosis, a diarrheal disease that can become chronic and life threatening in immunocompromised and malnourished people. There is no effective drug treatment for those most at risk of severe cryptosporidiosis. The disease pathology is due to a repeated cycle of host cell invasion and parasite replication that amplifies parasite numbers a...

Objectives Pyocyanin is a blue-greenish redox-active pigment, produced by Pseudomonas aeruginosa, with a wide range of biological and biotechnological applications. Pyocyanin biosynthesis is regulated by the quorum-sensing (QS) system in which the expression of QS genes and QS-controlled virulence genes may be affected by serum as a complex medium. In the current study, effects of adult bovine ...

Cell culture requires a suitable medium and environment for in vivo conditions. Conditions are created by regulating temperature, pH, oxygen, CO2, osmotic pressure, surfaces to adhere cells, nutrients, vitamins, protection against toxic substances, hormones, growth factors that regulate cell differentiation. In general, good occurs at pH of 7.0 - 7.6. Fetal Bovine Serum (FBS) is one the supplem...

An alkaline agent, namely food additive grade calcium hydroxide (FdCa(OH)2) in solution at 0.17%, was evaluated for its bactericidal efficacies in chiller water with sodium hypochlorite (NaOCl) at a concentration of 200 ppm total residual chlorine. Without organic material presence, NaOCl could inactivate Salmonella Infantis and Escherichia coli within 5 sec, but in the presence of fetal bovine...

Heparin at a concentration of 100 micrograms/ml, inhibits neonatal rat astrocyte proliferation by 45%, and [3H]thymidine incorporation into DNA by 55% when they are stimulated with 2% fetal bovine serum (FBS) in culture. Higher serum concentrations up to 10% FBS decreased this inhibition to 20% and 29% respectively. Inhibition of [3H]thymidine incorporation by heparin is dose-dependent with max...

Introduction Cryopreservation of the cells allows great flexible application for cell therapy, as well as industrial production of biologics such as antibody therapeutics. Conventionally, cryopreservative solution contains both of fetal bovine serum (FBS) and dimethyl sulfoxide (DMSO) as a cryoprotectant [1]. However, both of them have problems. FBS frequently induces differentiation of stem ce...

Background Follicle stimulating hormone (FSH) produced in recombinant Chinese hamster ovary (CHO) cells used for infertility treatment. Fetal Bovine Serum (FBS) in known as a factor in medium culture that provides the tolerance towards physiochemical variations and protects cells against apoptosis; on the other hand, FBS is the most expensive component in medium culture and collection that caus...
