Cellularity of adipose tissue in fetal pig
F Desnoyers, G Pascal, M Etienne and N Vodovar
Adipose tissue cellularity was studied in the 85-day-old Large-White pig
fetus. The aim of this work was to count the adipose cells of forming
tissue in an animal species which could be a possible model for studying
adipose tissue in humans. Using a morphometric method with electron
microscopy, mean triglyceride volume per cell was determined independently
of mean cell volume. This method is suitable for counting adipose cells in
the early stage of differentiation whatever their size and lipid inclusion
volume. Site-by-site dissection of adipose tissue was not feasible in the
85-day old fetus and adipose cell number was computed by dividing total
carcass triglyceride volume by mean triglyceride volume per cell. The
carcass triglyceride seemed to originate only from adipose cells. The mean
total carcass triglyceride volume per fetus (1.84 g) was low but, owing to
the low mean triglyceride volume per cell (180.28 microns3), the adipose
cell number (11.15 X 10(9)) was relatively important, as it represented
about 27% of the extramuscular adipose cell number in the Large-White adult
pig (41 X 10(9)).
