|
fibroblast
|
arise form mesenchymal cells
differentiate into chondrocytes, osteoblasts, adipose cells can be active fibroblast or quiescent (small, flattened) |
|
|
pericytes
|
derived embyronic mesenchymal cells; possible pleuripotent role
|
|
|
adipose cells
|
arise form mesenchymal cells (maybe fibroblast); fully differentiated
uniloculuar adipose cells: single fat droplet, cytoplasm and nucleus squeezed into periphery; cells have receptors for insulin, GH, norepi, and glucocorticoids secrete lipoprotein lipase which hydrolyzes chylomicrons into glycerol + fatty acids. These are then uptaken. Stored triglycerides are hydrolyzed by hormone-sensitive lipase (Activated by cAMP); fatty acids releated into ECM and lumen Secretes leptin (triggers inc energy consumption, reduce appetite) |
|
|
mast cells
|
arise for myeloid stem cells
|
|
|
Mucous tissue: wharton's jelly
|
loose connective tissue main constituent of umbilical cord
|
|
|
Dense connective tissue
|
More fibers, fewer cells
Dense regular: only present in tendons and ligaments Dense irregular: present in capsules + dermis |
