that had been manipulated at different stages of their development.From the first 3 figures we can see that specific stages during a new neuron’s development are associated with enhanced plasticity, unique neurotransmitter profiles and increased likelihood of cell death.

³H-thymidine (old school), Brd U (tried and true – example), or a GFP-expressing retrovirus (new school).For example: ——————————————————————— Hopefully it’s now clear that a 3 day-old neuron differs from a 3-week-old neuron from a 3-month-old neuron.We have seen examples where the developmental stage of a new neuron influences it’s functional maturation and survival, clues that could someday be used to manipulate adult neurogenesis for therapeutic purposes.Indeed, if you know these studies already, a brief look at the graphs will bring back the take home message.However, since the data is stripped of text, if the studies are unfamiliar, you’ll have to go to the original source to figure out what the heck they mean (use Pubmed to at least obtain abstracts for the original studies if I didn’t provide a direct link).

If you take a single time point out of some of these studies, say the % of new neurons that have excitatory glutamatergic inputs at 14 days-old in Esposito 2005 and Ge 2006, you might wonder, who’s right here? I curious as to why they differ but I still trust both of these studies and refer to them often because, within their respective timecourses, both 14-day data points make sense and, across studies, the 2 timecourses themselves do generally agree, even if they are slightly shifted.

Bromodeoxyuridine is a synthetic nucleoside that is an analog of thymidine. BrdU is commonly used in the detection of proliferating cells in living tissues. 5-Bromodeoxycytidine is deaminated to form BrdU. BrdU can be incorporated into the newly synthesized DNA of replicating cells during the S phase of the cell cycle.

In vivo, it has been used to identify the “birthdate” of cells during development, to examine the fate of postnatally generated cells, and to label cells before transplantation, for subsequent identification. Key Words BrdU labeling; birthdating; neurogenesis; gliogenesis; double labeling. 1. Introduction. Bromodeoxyuridine.

However, one of the first studies reporting the use of dual birthdate labeling in the brain used BrdU and IdU in human patients Hoshino et al. 1992. The authors injected brain tumors patients with BrdU, followed 5 h later by IdU. The percentage of BrdU+ cells was used to establish the S phase fraction, while the IdU/BrdU.

Why BrdU? In order to determine whether the brain is undergoing neurogenesis, scientists needed to devise a way to mark proliferating cells. One way to do this is to identify cells that are in the S phase – also known as the “synthesis” phase – of replication. Here, new copies of DNA are synthesized so that the cell may.
