Mitochondria and Fate

When neurons are produced they're generated from progenitor (committed precursor) cell-division, but this division isn't equal (it's asymmetrical) – the contents of the dividing cell is distributed asymmetrically into the resulting two daughter cells. One becomes the differentiated neuron, the other stays in the pool of progenitors. By cell fate tracking in living embryonic chick tissue, this study shows that the unequal distribution of mitochondria (the cell's energy source generating organelles) underlies this asymmetric outcome – the cell with fewer mitochondria than its sister consistently differentiates into a neuron

Holding Steady

Before a mammalian cell divides, the spindle -- a protein structure -- divides the cell's genetic material in two. As it does, the cytoplasm inside the cell forms a toroidal flow.

Last night I randomly joked about bunnies that could reproduce by budding off smaller bunnies, like amoebas. Roommate suggested that I should draw a "bunoeba," describing it as looking like an amoeba with bunny ears and teeth... and I added that to the "stuff to draw" note in my phone almost immediately. 😅

Tonight, I went back to the most recent half-full page of my notebook and filled up the rest with these little guys!

First there was the Pudding (cat ooze), and I've joked about a Gelatinous Cub (bear ooze) before, though I don't think I've ever actually drawn one. I guess now there's another member of the "cute critter, but it's also a blob" family. What critter will become goo next...?
