Question

Basal lamina is made up of ............???​

Answer 1

The basal lamina consists of a mixture of collagens, laminin (glycoprotein), perlecan (heparan sulphate glycoprotein), entactin (glycoprotein). These proteins can bind to each other to make a highly crosslinked extracellular matrix as shown in this diagram.

Answer 2

Answer:

Basal laminas are composed of a lattice-type network of type IV collagen intertwined with a network of laminin. This structure is stabilized by the binding of entactin/nidogen to the collagen and laminin. The heparan sulfate proteoglycan perlecan and other molecules are associated with the type IV collagen-laminin backbone.
