Lesson Summary Together, your sweat and sebaceous glands protect, condition and cool your skin surface. The extracellular matrix can be thought of as a suspension of macromolecules that supports everything from local tissue growth to the maintenance of an entire organ. Henrietta Lacks (born Loretta Pleasant; August 1, 1920 October 4, 1951) was an African-American woman whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line and one of the most important cell lines in medical research. The mission of Urology , the "Gold Journal," is to provide practical, timely, and relevant clinical and scientific information to physicians and researchers practicing the art of urology worldwide; to promote equity and diversity among authors, reviewers, and editors; to provide a platform for discussion of current ideas in urologic education, patient engagement, Characteristics of eukaryotic cells.
