The Beauty Within. A pair of tulips? Berries? What does this look like to you?
You’ll never guess the identity of this award winning image from the 2011 Olympus BioScapes competition.
This is an image of the ovaries and oviducts of the fruit fly Drosophila melanogaster. It is one of the best systems for studying basic stem cell biology. Each ovary has 12-16 ovarioles. Stem cells are located in a niche, the most apical part, known as germarium. There are three types of stem cells: germline stem cells (GSCs), somatic stem cells (SSCs) and newly identified escort stem cells (ESCs), whose activities have been confirmed by lineage tracing and laser ablation experiments.

Beautiful
that is outstanding!
Just don’t understand why money is wasted on fruit fly research!
Great info, thanks.

Thank you, Feisal Kamil , I’ve deleted Vinay Kumar ‘s comments. I spend a few minutes each day deleting the inane Hi’s and Your nice (no apostrophe!), usually from Indian dudes who lay particular claim to this brand of obnoxiousness. 🙂
I did flag those comments, what a creep.
T H Morgan spent his lifetime doing many test crosses on D. Melanogaster, i remember extracting salivary glands from 3 rd instar larvae of D melanogaster to study lampbrush chromosome
Yep, I would have guessed flowers, probably pre-disposed in that direction today!
wow.. !
