Primary culture of mouse embryonic spinal cord neurons: cell composition and suitability for axonal regeneration studies.

Primary culture is an effective experimental model to study molecular mechanisms that drive axonal regeneration after central nervous system injury. However, the culture of spinal cord (SC) cells remains poorly characterized. Here, we have analyzed the cell composition of a primary SC culture during its maturation.

[Development of national and international standards of population age distribution for medical statistics, health-demographic analysis and risk assessment].

The current European standard (CES) and the World population age distribution standard is widely used in medical and demographic studies, performed by international (WHO, etc.) and national organizations. The Russian Federal Service of States Statistics (RosStat) uses CES in demographic yearbooks and other publications.
