Genetic aspects of the temporal patterning of cortical neurogenesis
During corticogenesis, distinct subtypes of neurons are sequentially born from ventricular zone progenitors. How these cells are molecularly temporally patterned is unknown. Here, we use high temporal resolution single-cell RNA sequencing to lineage-trace the molecular identities of successive generations of apical progenitors (APs) and their daughter neurons in mouse embryos.
We identify a core set of evolutionarily-conserved, temporally-patterned genes, which drive APs from internally-driven to more exteroceptive states, and reveal that the polycomb repressor complex PRC2 epigenetically regulates AP temporal progression. Embryonic age-dependent AP molecular states are transmitted to their progeny as successive ground states, onto which essentially conserved early post-mitotic differentiation programs are applied, and complemented by later occurring environment-dependent signals.
Thus, epigenetically-regulated temporal molecular birthmarks present in progenitors act in their post-mitotic progeny to seed adult neuronal diversity.

University of Turin, Italy
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.
