Which cells produce collagen and elastin?

Fibroblasts are the primary cells responsible for producing collagen and elastin, which are essential components of the extracellular matrix. Collagen provides structure and strength to tissues, while elastin offers elasticity, allowing tissues to return to their original shape after stretching.

Fibroblasts are found throughout connective tissues in the body and play a crucial role in wound healing and tissue maintenance. Their ability to synthesize these proteins is vital for maintaining the integrity and flexibility of the skin and other organs.

The other options refer to different types of cells or structures. Melanocytes are responsible for producing melanin, the pigment that gives color to the skin and hair. Melanosomes are organelles within melanocytes that store and transport melanin. Hyaluronic refers to hyaluronic acid, which is a substance that helps retain moisture in the skin and is not a cell type responsible for producing collagen or elastin.
