Background: Fibroblasts are mesenchymal cells that can be readily cultured in the laboratory and play a significant role in epithelialmesenchymal interactions, secreting various growth factors and cytokines that have a direct effect on epidermal proliferation, differentiation and formation of extracellular matrix. They have been incorporated into various tissue-engineered and used for a variety...

purpose: this study evaluated the effect of donor and eye bank characteristics on graft rating and clinical outcomes after penetrating keratoplasty (pk) in keratoconus-affected patients. methods: a total of 252 consecutive keratoconic eyes that underwent pk were reviewed in this retrospective interventional case series. donor data included age and sex, cause of death, death-to-preservation time...

background and aims: during the last years a new foreskin cell line strain (rfsc) has been isolated, characterized and stored in a representative cell bank stock in liquid nitrogen as a part of hcb (human cell bank) development program in razi institute. materials and methods: the cell population was serially passaged for mass production purpose based on who schedule .the controls on pool sampl...

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being exploited. Mathematical analysis has shown that a fla...

Cord blood is a sample of blood taken from a newborn baby's umbilical cord.Cord blood is collected because it is rich in stem cells content, such as hematopoietic cells, which can be used to treat hematopoietic and genetic disorders. Cord Blood Transplantation has been used in the treatment of over 80 diseases, including leukemia, lymphoma and anemia. Advantages of Cord Blood Treatment: • ...
