Biopsy reveals sheets of
chondroblast with background of chondroid matrix.
Failure of this process initiates
chondroblast and osteoclast activity and subsequent graft tissue absorption [26].
Some authors suggested that FeLV may be related to the etiology of feline osteochondromas (POOL & CARRIG, 1972; DOIGE, 1987; ROSA & KIRBERGER, 2012), and viral particles have been observed in proliferated
chondroblast membranes (POOL & CARRIG, 1972).
Ultrastructurally Cells show primitive features to mature features ranging from prelipoblast and
chondroblast, to lipoblast and preadpoytes, to mature adipocyte.

(13) Histologically, the basic proliferating cell is
chondroblast, which has distinct oval nuclei with longitudinal groove.
IGF-I and IGF-II increases proliferation and differentiation of bone marrow progenitors to osteoblast and
chondroblast (Singh et al., 2007d) and myogenic satellite cells to adipoblast (Singh et al., 2007c) in vitro.
Chondroblast (a), chondrocyte (b), from tendon with cartilago sesamoidea.
In chondrosarcoma, the smears were cellular and contain
chondroblast, chondroid matrix forming amorphus background in the smear.
