Measures of adipocyte size: diameter, area, volume.
ADIPOCYTE_SIZEA data.frame with 55825 rows and 7 variables:
pidinteger; randomly generated 8-digit identifier used in linkage to phenotypic data. All samples from the same animal have the same PID.
factor; the sex of the rat with 2 levels "Female" and "Male".
factor; exercise training group. Either "SED" (sedentary) or the number of weeks of training ("1W", "2W", "4W", "8W").
numeric; adipocyte diameter in microns.
ordered factor; diameter binned in approximately 5 micron intervals.
numeric; adipocyte area in square microns.
volume; adipocyte volume in cubic microns.
integer; total number of adipocytes across all images for a particular animal.
Adipocyte area was calculated using CellProfiler. Diameter was derived from area, under the assumption of circular cross-sections. Volume was derived from area, under the assumption of spherical adipocytes.
