## Abstract In this study we examined the different aspects of the pathway leading to the differentiation of keratinocytes as a function of time in culture and calcium concentration of the culture medium. Human neonatal foreskin keratinocytes were grown in a serum‐free, defined medium containing 0.

✦ Synopsis
The effect of transforming growth factor-type f3 l(TGF-P) on the growth and differentiation of normal human skin keratinocytes cultured in serum-free medium was investigated. TCF-P markedly inhibited the growth of keratinocytes at the concentrations >2 ng/ml under low Ca2+ conditions (0.1 mM). Growth inhibition was accompanied by changes in cell functions related to proliferation. Remarkable inhibition of DNA synthesis was demonstrated by the decrease of

The stimulation of DNA synthesis by epidermal growth factor (EGF) has been studied for a cell line having properties useful for investigating the mechanism of action of EGF in epithelial cell populations. These studies employ a mouse keratinocyte cell line (MK), isolated by Weissman and Aaronson (1
Extensive skin loss from a variety of conditions such as severe thermal injury is associated with significant functional morbidity and mortality. In recent years, the healing quality has been improved for patients who suffer burns due in part to the usage of skin replacement mainly prepared from mul
Transforming growth factor β 1 (TGF-β 1 ) has been implicated as inhibitor of cell proliferation and a potent inducer of apoptosis in vitro and in vivo after the administration of high doses. To assess the role of endogenous TGF-β 1 , we quantitated the cytokine and its receptors in rat liver during
## Abstract The vascular cell responses to the type 1, 2, and 3 isoforms of transforming growth factor‐β (TGF‐β1, TGF‐β2, TGF‐β3) were studied using bovine aortic endothelial (BAECs) and smooth muscle cells (BASMC3) as well as rat epididymal fat pad microvascular endothelia (RFCs). Three distinct b
Corneal epithelial stem cells and transient amplifying cells are located in the limbal and corneal regions, respectively. In a serum-free medium with or without different cytokines, limbal fibroblasts consistently produced greater levels of keratinocyte growth factor (KGF) transcript and protein tha
