Details
Human Transforming Growth Factor beta 1 (TGF-b1) - Transforming Growth Factor (TGF) plays a crucial role in tissue regeneration, cell differentiation, embryonic development, and regulation of the immune system. Transforming growth factor beta is found in hematopoietic (blood-forming) tissue and initiates a signaling pathway that suppresses the early development of cancer cells. It enhances the deposition of extracellular matrix and may play potential role in wound healing and cirrhosis formation. Many cells synthesize TGF-b and almost all of them have specific receptors for this peptide.
