Cellular and Molecular Characterization of Multipolar Map5-Expressing Cells: A Subset of Newly Generated, Stage-Specific Parenchymal Cells in the Mammalian Central Nervous System
Paola Crociara, Roberta Parolisi, Daniele Conte, Marta Fumagalli, Luca Bonfanti
Although extremely interesting in adult neuro-glio-genesis and promising as an endogenous source for repair, parenchymal progenitors remain largely obscure in their identity and physiology, due to a scarce availability of stage-specific markers.
What appears difficult is the distinction between real cell populations and various differentiation stages of the same population. Here we focused on a subset of multipolar, polydendrocyte-like cells (mMap5 cells) expressing the microtubule associated protein 5 (Map5), which is known to be present in most neurons.
We characterized the morphology, phenotype, regional distribution, proliferative dynamics, and stage-specific marker expression of these cells in the rabbit and mouse CNS, also assessing their existence in other mammalian species. mMap5 cells were never found to co-express the Ng2 antigen. They appear to be a population of glial cells sharing features but also differences with Ng2+progenitor cells.
We show that mMap5 cells are newly generated, postmitotic parenchymal elements of the oligodendroglial lineage, thus being a stage-specific population of polydendrocytes. Finally, we report that the number of mMap5 cells, although reduced within the brain of adult/old animals, can increase in neurodegenerative and traumatic conditions.

The Workshop is aimed at PhD students and young Postdocs with the goal to promote a thorough understanding of the functions of glial cells in health and disease. The program includes lectures on the newest conceptual advancements and methodological approaches in the study of glial cells in synaptic functions, development and CNS diseases.
Deadline for registration: December 23, 2019.

Una notizia che abbiamo letto tutti di recente sui giornali. Noi del NICO abbiamo la fortuna di collaborare da anni con il dott. Bruno Battiston e il prof. Diego Garbossa - i chirurghi che hanno svolto l'operazione - e ci siamo fatti spiegare bene in cosa consiste l’intervento, quale era la situazione del paziente e quali saranno i possibili risultati.
Tutto questo al di là delle semplificazioni e dei titoli roboanti dei giornali, comprensibilmente utilizzati per attirare l’attenzione dei lettori.
