[Nuclear proteins and nucleic acids during differentiation of neurons in the spinal cord ganglia, spinal cord and tectum opticum in chickens. Cytophotometric study with computation programs].

By means of doublewave cytophotometry of the histological sections and smears performed with the device mtsfv-1 (lomo) it has been demonstrated that differentiation of some neurons of the spinal ganglia and the spinal cord is accompanied with hyperreplication of DNA amount exceeding the diploid contents, while the large neurons in layer III of the tectum opticum remain diploid. In the process of differentiation an increased amount of RNA and histones, and decreasing portion of histones sented for the microcalculator b3-21.
