What do fibroblasts produce during the repair phase of wound healing?

During the repair phase of wound healing, fibroblasts play a crucial role by producing collagen. Collagen is a fundamental structural protein in the body that provides strength, support, and integrity to connective tissues, including skin, ligaments, and tendons. As wounds heal, collagen forms a scaffold that allows new tissue to grow and repair the damaged area. It is essential for the formation of granulation tissue, which is an important part of the healing process and helps bring about the replacement of lost tissue.

While other substances, such as elastic fibers, keratin, and adipose tissue, are important in different contexts within the body, they are not directly produced by fibroblasts during the repair phase of wound healing. Elastic fibers contribute to the elasticity of tissues, keratin is vital for the structure of the skin and hair, and adipose tissue serves as energy storage and insulation. However, in the context of the immediate wound healing process, collagen is the primary product of fibroblasts.
