progenitor

With some of the screened AAV variants, the researchers can label progenitor cells at a specific point in time during the circuit's development and follow them to see what neurons they become.

Because these "progenitor" T cells retain tremendous anti-tumor potential, there is great interest in determining how to maintain them and the mechanisms that promote their transition into the non-functional exhausted T cell.

With its truncheonlike guitar riff and haunting aura that called to mind a rock ’n’ roll “Dies Irae,” the song is considered a progenitor of heavy metal and encapsulated Mr. Ingle’s ambition at the time:

Herders sometimes favor hybridization because genes from wild progenitors are thought to enhance the hardiness of domestic stock.

The study explored a rare form of mast cells called myeloid progenitors in blood, in patients with the condition.
