Abstract

Author's studies and literature references indicate that the DNA-binding cytokine: amphoterine, being a non-histone component of chromatin, acts in extracellular milieu as cytokine regulating gene expression in target cells. The amphoterine effects are mediated by its interaction with the cell surface receptors including those of the final glucosiding product (RAGE), which leads to activation of the ERK and p38 MAP-kinases as well as NF-kappaB. Amphoterine prompts inflammatory response by means of activating synthesis of interleukins-1, -6 and -8 as well as tumour necrosis factors (TNF-alpha) and activates tissue regeneration by means of involvement of the precursor cells into the damage foci and induction of the cells' differentiation. These properties of amphoterine suggest that appearance of this protein in extracellular space signals of a tissue damaging.

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.
