ADENOSINE TRIPHOSPHATASE AND 5-NUCLEOTIDASE IN SPINAL CORD.HISTOCHEMICAL STUDY OF LOCALIZATION IN RAT SPINAL CORD.

<h3>Introduction</h3> Previous studies on the distribution of adenosine triphosphatase (ATPase) have been carried out mostly on paraffin sections and have resulted largely in a critical analysis of methodology rather than in an interpretation of the results. The biochemical studies by Robin and Smith¹⁸showed significant variation in the chemical composition of different parts of the gray areas of the central nervous system, and those of Naidoo and Pratt¹⁵yielded different results under different conditions. Although the enzymes have been studied histochemically in brain stem,⁶cerebral cortex,^11,15and spinal ganglia and cerebellum,^21,22little has been done so far on the spinal cord. The present work was undertaken on cryostat sections and using the enzyme techniques currently in favor. <h3>Material and Method</h3> Healthy young adult rats were killed by decapitation without anesthesia, and the pieces of spinal cord, mostly from the cervical and thoracic regions, were taken

In vitro induction of cartilage in mouse somite mesoderm by embryonic spinal cord.

Somite mesoderm from the anterior region of mouse embryos possessing fewer than 25 somites fails to produce cartilage or bone either in culture or on subsequent implantation into the anterior chamber of the eye. When combined in culture with pieces of spinal cord from the same stage embryos, however, the mesoderm differentiates cartilage nodules in culture and produces bone including hematopoietic tissue, adipose tissue and occasional lymphoid tissue on implantation into the eye.
