Scanning electron microscopy of the developing renal glomerulus

The constant progress in histological technology opens up new possibilities in morphogenetic research, particularly when a three-dimensional picture is desirable. In the present study a retrograde vascular fixation, methacrylate casts of blood vessels and scanning electron microscopy have been used to reconsider the earlier observations on the development and differentiation of the renal glomerulus in the kidney of the new-born rat.
