basement membrane

The basement membrane is a thin, specialized layer of extracellular material located beneath cells in our tissues. It acts as a supportive foundation, anchoring the cells to underlying structures like connective tissue. This membrane also helps regulate what substances can pass between tissues, contributing to tissue stability and filtering processes. Formed mainly of proteins and fibers, the basement membrane is essential for maintaining tissue organization, guiding cell growth, and facilitating repair after injury. Its integrity is vital for overall tissue function and health.
