Please explain what is meant by hemidesmosomes. ???
Hemidesmosomes are mainly called as anchoring junctions between the basal lamina and the bases of epithelial cells. Ultrastructurally, they resemble a single-sided desmosome, anchored on one side to the plasma membrane, and on the other to the adjacent collagen fibrils and basal lamina. Hemidesmosomes use integrins as their adhesion molecules. Hope you got the answer. ALL THE BEST..
@ akansha 1- hemidesmosomes are a small rivet like structure found in the inner basal surface of the keratinocytes in the epidermis of skin . 2- they are simmilar to desmosomes when viewed under electron microscopy ., 3- desmosomes link two cells together but hemidesmosomes link 1 cell to the extracellular matrix . 4- they are asymmetrical in nature and are found in epithellial cells . HOPE IT CLEARS YOUR DOUBT ALL THE BEST ..
