Fibroblasts are a type of cell that plays a critical role in wound healing and tissue repair. They are found within connective tissue and are responsible for producing collagen, a key component of the extracellular matrix that helps provide support and structure to tissues. In research, fibroblasts are studied for their role in various diseases and conditions, such as cancer, fibrosis, and aging. Researchers investigate the function of fibroblasts, their interactions with other cells, and potential therapeutic interventions targeting these cells. Overall, understanding fibroblasts is important for advancing our knowledge of tissue regeneration and disease progression.
