| The pronephroi (plural of pronephros), also known as the head kidneys, are labeled blue in the above sample due to the uptake of fluorescent proteins from the blood. Xenopus pronephroi leak large amounts of protein during glomeral filtration which are later recovered by transepithelial transport. See Zhou and Vize 2004 for details. | Dynamic Java model of pronephros. Click and drag on the kidney to rotate or roll. The different segments of the pronephric tubules are labeled on one side. The unlabeled pronephric tubules are yellow. The glomus is shown in green. For a larger model see the contributing 3D kidney page. For details on this technology visit the 3D site. |
