astroblastn.

Brit.

/ˈastrə(ʊ)blɑːst/,

/ˈastrə(ʊ)blast/, U.S.

/ˈæstrəˌblæst/,

/ˈæstroʊˌblæst/

Origin: Formed within English, by compounding. Etymons: astro- comb. form, -blast comb. form.

Etymology: < astro- comb. form (see astro- comb. form 2) + -blast comb. form. In sense 2 after German Astroblast (1895 or earlier).

Histology.

†1. A type of star-shaped cell (not identified); (perhaps) a bone cell (cf. astrocyte n. 1). Obsolete. rare.

1871 C. F. Rodenstein in N.Y. Med. Jrnl. 14 607 There is a physiological tendency which causes one cell to become an astroblast, and another of identical structure to become a connective-tissue corpuscle.

2. An immature precursor of an astrocyte.
