Lipoblast features.

A lipoblast is a precursor cell for an adipocyte.[1]

Alternate terms include adipoblast[2] and preadipocyte.[3]

Early stages are almost indistinguishable from fibroblasts.[4]

  • Lipid-laden histiocytes may mimic lipoblasts, but have lightly eosinophilic cytoplasm and a small normochromatic nuclei which are not hollowed out from the lipid vacuoles.[6]

Liposarcoma

[edit]

Lipoblasts are seen in liposarcoma[7] and characteristically have abundant multivacuolated clear cytoplasm and a dark staining (hyperchromatic), indented nucleus.

One thought on “Cannabaceae”

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
