Proerythroblast - Wikipedia
A proerythroblast (or rubriblast, or pronormoblast) is a precursor cell to the normoblast (nucleated red blood cell), as the earliest of four stages in its development. In histology, it is very difficult to distinguish it from the other "-blast" cells (lymphoblast, myeloblast, monoblast, and megakaryoblast).

Erythroid maturation in bone marrow - eClinpath
May 25, 2017 · A: The earliest recognizable erythroid progenitor is the proerythroblast, which is recognized by a round nucleus, fine chromatin and deep blue cytoplasm (lots of RNA). This particular cell has an indistinct nucleolus and would be called a rubriblast in veterinary terms. B: Another version of a proerythroblast.
Stages of erythropoiesis - eClinpath
Apr 16, 2021 · As the red blood cells mature from the earliest identifiable cell (by morphology), the rubriblast or pro-erythroblast, it divides, creating new progeny, which are smaller and start to produce hemoglobin.

Proerythroblast - an overview | ScienceDirect Topics
Proerythroblast (rubriblast). In the earliest forms the cytoplasm stains light blue but in later, more prevalent forms, in association with the beginning formation of hemoglobin, there is a superimposed reddish tint that gives the cytoplasm a distinctive, dark, royal blue color.
Proerythroblast - CellWiki
Proerythroblast. Synonyms: Rubriblast, Pronormoblast. Proerythroblasts are the youngest erythroid progenitors. The nucleus is centrally located, has a fine chromatin pattern and is often almost perfectly round. The cytoplasm is deeply basophilic and has a dark border. The cell may have one to two "ears" .

The proerythroblasts, known also as pronormoblasts or rubriblasts, are the earliest precursors of erythropoiesis. They range from 15 to 22 μm in size and do not yet contain hemoglobin. Their cytoplasm is darkly basophilic and often shadowy. The nucleus exhibits...
