Would the body use this transferred fat for as energy, or would it
ignore it as it wasn't stored there in the first place?
It would use it as energy source, there is no such thing as "ignored tissue". Fatty acid mobilization is regulated by epinephrine and insulin. These are hormones which are ofc. carried by blood, so every white adipose (fat) tissue is affected by them.
Does the body differentiate fat cells stored in different parts of the body?
This is obvious, just check breasts and butts of girls. ;-) (Those are subcutaneous fat depos. They size is probably regulated by estrogen.)
There are other things involved here, we can talk about subcutaneous (fat below the skin), intramuscular (fat in the muscles) and visceral (abdominal fat) white adipose tissue (there are white, brown and beige adipose tissues). The visceral fat is associated with metabolic diseases, obesity etc...
The regulation of body fat distribution and amount is complicated and regulated differently by subcutaneous, intramuscular and visceral fat.
The total transmissible variance ranged from about 40 percent for the
amount of subcutaneous fat to 60 percent for the pattern of
subcutaneous fat distribution. Biological inheritance accounted for
only 5 percent of the variance for subcutaneous fat and the body mass
index, but 20 to 30 percent for the percentage of body fat, fat mass,
fat-free mass, and fat distribution. These data suggest that the
amount of internal fat is influenced by heredity more than the amount
of subcutaneous fat. Furthermore, we consistently found that
nongenetic influences are quite important in determining the amount
and distribution of body fat in the population.
These data suggest that adiponectin concentrations are determined by
intra-abdominal fat mass, with additional independent effects of age
and sex. Adiponectin could link intra-abdominal fat with insulin
resistance and an atherogenic lipoprotein profile.
The FFA storage pathway, which had remained undetected in
postabsorptive humans until recently, can have considerable,
long-term, and sex-specific effects on body fat distribution. It can
also offer a way of protecting the body from excessive circulating FFA
Different colors (white, brows, beige) and orgin (subcutaneous, intramuscular, visceral) originate from different progenitor cells.
These results reveal a major ontogenetic difference between visceral
and subcutaneous WAT, and pinpoint the lateral plate mesoderm as a
major source of visceral WAT. They also support the notion that
visceral WAT progenitors are heterogeneous, and suggest that
mesothelium is a source of adipocytes.
Brown and white adipocytes have been shown to derive from different
progenitors. In this study we sought to clarify the molecular
differences between human brown and white adipocyte progenitors cells.
The regulation of fat distribution is under research, and not fully understood yet.
Fat distribution differs in men and women, but in both sexes, a
predominantly gluteal-femoral compared with abdominal (central) fat
distribution is associated with lower metabolic risk. Differences in
cellular characteristics and metabolic functions of these depots have
been described, but the molecular mechanisms involved are not
