What Is In That Ear?
Discussion The external auditory canal mainly derives from the ectoderm however it abuts other structures which arise from mesodermal or endodermal tissues. The lateral 1/3 is primarily cartilaginous with the inner 2/3rd being bony with the tympanic, temporal and mastoid bone forming various parts. The canal is lined with squamous epithelium and has various structures such as sebaceous glands, hair follicles and of course ceruminous glands. It is not surprising that this structure is subject to obstruction given its small size. Cerumen, hair and other cellular debris may become impacted if they are not regularly expelled f...

UCLA scientists use stem cells to study genetics of germ cell tumors
UCLA researchers have made new inroads into understanding germ cell tumors, a diverse and rare group of cancers that begin in germ cells — the cells that develop into sperm and eggs. The researchers developed a protocol to recreate germ cell tumor cells from stem cells and used the new model to study the genetics of the cancer.Their findings could point the way toward new drugs to treat germ cell tumors, which account for around 3 percent of all cases of childhood and adolescent cancer.The study, published in Stem Cell Research, was led by Amander Clark, a UCLA professor of molecular cell and developmental biology and a ...
