Adipocyte, I’m looking at your structure. You have everything I understand to be in a human cell plus added oil bodies or lipid bodies. Drawing you out to know you better, I layer the lipid droplets in yellow and white. Fun to resolve this portion of you. I use casein paint and ink but I might have worked with egg tempera. I bet a simple droplet of egg yolk could suffice.

Adipose tissue, AKA body fat, located beneath the skin, around organs, between muscles, in bone marrow and in breast tissue. Can I really describe you as a major endocrine organ because…you produce hormones? Do I understand this correctly? I drew out all the major endocrine glands, do I go back to the series and add you now?
Adipocyte AKA Fat Cell
Adipocytes form several types of adipose tissue, at least 2 maybe 3.
One type: Brown adipose tissue (BAT) ↓
Brown adipose tissue, each of your cells includes several lipid droplets. And you hold many iron-containing mitochondria. Is this why you appear warm in color? Mitochondria, holders of energy (ATP), are the power-house of a cell. It is no wonder you consume energy and generate heat.
Brown Adipose Tissue (BAT)
Do you sit in the front and back of the neck and upper back? Between the shoulder blades? Around the kidneys? Anywhere else? And are you the baby-fat in a newborn?
Will you hang out and stay active as I get older? Please do! I need you for warmth and physical activity. I need you for my bones and for endurance.
Second type: White adipose tissue (WAT) ↓
White adipose tissue, I especially enjoy setting in your single lipid droplet (again, like dropping yolk to mix my egg tempera paint). I pull out my thinnest brushes and sharpen all my pencils to be able to detail organelles into each of your cell’s periphery. You might be simple in design, though I find you more complicated.
White Adipose Tissue (WAT)
You have fewer mitochondria than brown fat. You store energy in case I overexert (and in case of starvation). You too help maintain my body temperature. Do you hold heat? Are you more like insulation? Padding? Are you mostly visceral fat? Might I find you inside my abdominal cavity and between my organs? You don’t have my permission to take over my liver or intestines. And don’t get too comfy with my heart or kidney’s either. You’re a little more troublesome, aren’t you? And what does it mean that you originate from connective tissue?
Maybe a 3rd type is beige fat?
Sooo…I hear white fat can brown with chronic cold exposure. While out on my morning run, I consider the probability. Not happening in Phoenix. Though a friend did just tell me about a local gym that supports a cold therapy.
A few weeks ago:
I have lunch with Joe, a doctor/educator from New Mexico. We meet to discuss the microbiome. He directs the conversation towards weight gain. He says, with no uncertainty, everyone will gain weight with age. He explains why he believes this to be true.
Joe talks about people and the relationship they have with their microbiome which involves both cooperation and conflict. I appreciate when he explains humans are an eco-system. He adds… a sometimes messy eco-system.
The stuff that stays with me:
Weight gain might not always be about discipline or lack thereof.
There might be something else at play in the gaining of weight.
Perhaps gut microbes influence eating behavior.
I sense Joe’s compassion for people dealing with weight issues.
I take my drawings through a filter to contrast and simplify forms. Here is another view of the varying density of adipose tissue. #Ahh!Life!
