What Cells Secrete the Proteins That Make Up the Matrix

Question

What cells secrete the proteins that make up the matrix of loose connective tissue?
A) hepatocytes
B) fibroblasts
C) chondrocytes
D) osteocytes

Accepted Answer

Fibroblasts are the primary cells that secrete the extracellular matrix proteins, such as collagen and elastin, that make up the matrix of loose connective tissue. Hepatocytes are liver cells, chondrocytes are cartilage cells, and osteocytes are bone cells, and are not responsible for secreting the components of loose connective tissue.
