Fibroblasts

Ellen Merfeld and Allison Schollmeyer

Function

Maintains structural integrity of connective tissue by secreting proteins like collagens, glycosaminoglycans, and glycoproteins.

Organelles

Mitochondria- take in nutrients, breaks them down and creates energy for the cell

Golgi Apparatus- Modifies, sorts and packages proteins for secretion

Endoplasmic Reticulum- folds the protein molecules in sacs called cisternae and transports proteins to the Golgi Apparatus

Connective Tissue

Fibroblasts help to create connective tissue that supports, anchors and connects various parts of the body. The tissue holds all organs in place.

Skin

Dermal Fibroblasts in the skin-

  • Generates connective tissue that allows the skin to recover from injury
  • Produce protein molecules that comprise the extracellular matrix
  • Helps cells join together on the top layer of skin
