Which type of cells are crucial in the production of collagen?

Fibroblasts play a vital role in the production of collagen, which is a key structural protein in the extracellular matrix of connective tissues. These cells are responsible for synthesizing collagen fibers and other extracellular matrix components, which provide support and strength to tissues such as skin, tendons, ligaments, and cartilage. Fibroblasts also aid in wound healing and tissue repair by producing various proteins that facilitate regeneration.

In contrast, keratinocytes are primarily involved in the formation of the outer layer of skin and are responsible for producing keratin, a protective protein. Adipocytes are specialized cells for storing fat and are not involved in collagen production. Immune cells play critical roles in protecting the body from pathogens and managing inflammation but do not produce collagen. Thus, fibroblasts are the essential cells linked directly to collagen synthesis.
