Active proliferation in a number of epithelial tissues is associated with increased or " de novo" 14. The CCL25 chemokine is prevalent in the epithelial tissue of the small intestine ( 7 ). 15. Vitamin A is a fat-soluble vitamin necessary for growth, reproduction, differentiation of epithelial tissues , and vision. 16. The epitheloid would then have served as the precursor to the true epithelial tissue of the eumetazoans. 17. Epithelial tissue lines surfaces throughout the body.18. The epithelial tissue emerging from this MET process eventually forms the tubules and glomeruli of the nephron. 19. The walls of the hollow cochlea are made of bone, with a thin, delicate lining of epithelial tissue . 20. Epithelial tissue and connective tissue formed from several fibers of collagen are the main components of these layers.
