Human Embryology and Morphology

Ultrastructural features of chondrogenesis in the human hand plate: a cytochemical and autoradiographic study.

The generation of the three-dimensional model of the human knee joint.

In this paper we analyze the anatomic elements that compose the human knee joint. Also, we build the spatial model of the human knee joint components. This study is necessary for the design of prosthesis elements and for the establishment of the necessary prosthesis technique.

Growth of 9.5-day rat embryos in human serum.

Rat embryos were explanted at 9.5 days and cultured for 48 h in human serum supplemented with glucose. The embryos were anaemic and frequently malformed. The haemoglobin and DNA content of these embryos was less than those grown in pure rat serum. Addition of 10% rat serum improved the embryonic growth as well as the haemoglobin and DNA content. This suggests that rat serum provides essential g...

The early development of morphology and patterns of the face in the human embryo.

When there are many people who don't need to expect something more than the benefits to take, we will suggest you to have willing to reach all benefits. Be sure and surely do to take this the early development of morphology and patterns of the face in the human embryo that gives the best reasons to read. When you really need to get the reason why, this the early development of morphology and pa...

Protein transmission across the rabbit foetal membranes.

The signal from fruiting body and conus tips of Dictyostelium discoideum.

Tips from fruiting bodies and conuses were transplanted into interphase fields of Dictyostelium discoideum amoebae. Progressively increasing concentrations of beef-heart phosphodiesterase added to the fields significantly decreased the chemotactic range of the responding amoebae. The findings suggest that the tip secretes c-AMP. We also find that the chemotactic range is independent of the size...
