The siphuncle of the chambered nautilus (Nautilus spp) can transport cameral liquid against osmotic pressure gradients, and is presumed to be able to transport against hydrostatic pressure gradients. It is hypothesized that the mechanism of such tran

The effect of developmental stage on chondrogenic capacity in high-density cell cultures of chick embryonic wing bud mesenchyme is examined. Mesenchyme from stage 19 embryos forms aggregates of closely associated cells which do not form cartilage mat

The development and localization of the mesenchymal extracellular matrix (ECM) in the early embryonic chick wing was studied by TEM using a fixative which enhanced the preservation of glycosaminoglycans, especially hyaluronic acid (HA) (Singley and S

In order to explain the observation that normally nonchondrogenic limb mesenchyme forms extensive cartilage in culture, the possibility that limb ectoderm inhibits chondrogenesis is examined. Small pieces of quail or chick ectoderm are grafted onto m

The development of the sclerotome is considered as a model for the formation of mesenchyme from an epithelium. In early epithelial somites, transmission and scanning electron microscopy indicate considerable ultrastructural similarity between the fut

A quantitative comparison (i.e., number of cartilage nodules) of cartilage differentiation was made between micromass cell cultures prepared with cells from different locations (core vs periphery) within prechondrogenic chick wing buds. Wing bud core

This study describes a method, which makes use of tannic acid (2%) as a component of a paraformaldehyde-glutaraldehyde based fixative, to reveal the presence and ultrastructure of glycosaminoglycans in the extracellular matrix. The ultrastructure of

This study demonstrates that the dorsal ectoderm of the stage 14 chick embryo synthesizes hyaluronic acid. About 49 to 52% of the H3 glucosamine-labeled glycosaminoglycan that is synthesized by explanted ectoderm can be identified as hyaluronic acid
