Abstract:
Some of the many cell-surface antigens defined by the CD (cluster differentiation) nomenclature have lately emerged as proteins with well-characterised enzymic activities. One important example is CD10 or CALLA (common acute lymphoblastic leukaemia antigen), which is identical to endopeptidase-24.11, an enzyme with an important role in the hydrolysis of biologically active peptides. CD13 and CD26 are also surface peptidases. These enzymes, which have a wide distribution on the surfaces of various cell types, may have specific roles in the control of growth and differentiation in both haemopoietic and epithelial cell systems.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
