vascular bed consists of a dense irregular network of sinusoids in direct contact with the
growth cartilage, supplied by end-arteries, and drained by a profusion of metaphysial
sinusoids. 2. The circulation is a closed one–that is, the endothelium is unbroken in its
continuity and microhaemorrhages do not occur against the cartilage. 3. It is possible that
juxta-epiphysial endothelial cells or their derivatives are chondrolytic, and that they …

1. The results of the present investigation indicate that in the foetal rat the juxta-epiphysial vascular bed consists of a dense irregular network of sinusoids in direct contact with the growth cartilage, supplied by end-arteries, and drained by a profusion of metaphysial sinusoids.
2. The circulation is a closed one–that is, the endothelium is unbroken in its continuity and microhaemorrhages do not occur against the cartilage.
3. It is possible that juxta-epiphysial endothelial cells or their derivatives are chondrolytic, and that they participate directly, together with other mesenchymal derivatives, in the removal of cartilage as a preparatory stage in enchondral bone formation.
