Urinary Tract Fibroblasts (UTF)

Urinary tract fibroclasts originate from urinary tract tissue. Fibroblasts have a spindle shaped or irregular triangular cell body with an oval shaped nucleus in the center, cytoplasmic protrusion, and a radial shape during growth. Fibroblasts cultured in vitro are mostly spindle shaped, polygonal, and flat star shaped, and their morphology can still change depending on the functional changes of the cells and the physical properties of their attachment sites. Under electron microscopy, abundant rough endoplasmic reticulum, free ribosomes, and developed Golgi complexes can be observed in its cytoplasm. Fibroblasts that are in a mature or stationary state have a smaller cell body in a long spindle shape, with underdeveloped rough endoplasmic reticulum and Golgi complex. It has strong ability to divide and proliferate, strong adaptability, and is one of the easiest types of animal cells to cultivate.
