FGF-1, or Fibroblast Growth Factor 1, is a protein that plays a crucial role in various biological processes, including cell growth, development, and tissue repair. It is part of the FGF family, which consists of several proteins that help regulate cell functions and promote angiogenesis, the formation of new blood vessels. This growth factor is particularly important in wound healing and has been studied for its potential therapeutic applications in regenerative medicine. Researchers are exploring its use in treating conditions such as diabetes and cardiovascular diseases, where promoting tissue regeneration and improving blood flow can be beneficial.
