Concomitantly, the germinal-layer cells and PSCs produce exosomes and extracellular vesicles that carry proteins such as antigen B2 and TSPAN14 [32], and non-coding RNAs involved in mediating the inflammatory response and the collagen catabolic process [33], which could modulate these differential CE cyst phenotypes. The gene discussed is TSPAN14; the disease is cholesteryl ester measurement.
