High impact information on mmp9

  • These results suggest that mmp9 will serve as a useful marker of mature myeloid cells in the zebrafish [1].
  • Maternal transcripts of mmp9 are deposited in the oocyte and dispersed throughout the early embryo [1].
  • From 24h post fertilization, mmp9 expression was detected in a population of circulating white blood cells that are distinct from macrophages, and which migrate to the site of trauma, and so likely represent zebrafish heterophils [1].

Anatomical context of mmp9

  • In the adult, mmp9 expression was most prominent in the splenic cords, a site occupied by mature myeloid cells in other species [1].
