I believe I just traded chicken coop plans and advice for a protocol on how to make bone marrow chimeric mice.
This also speaks to my ability (and perhaps to an inevitability in life) to do good and bad things at the same time. Extinguish life, nurture life. Experiment on mice, save chickens from factory farm fate. Kill mice, save kids from malaria (eventually). Make husbandry mistakes and watch my chickens keel over from unknown causes, save (a small part of) the environment.
I’m finding the key is to be very good and efficient at the bad things so you don’t have to do them often. If I make my bone marrow chimeras well, they won’t die by accident and I won’t have to repeat the experiment. Make their little lives count!
Gawd I hate bone marrow chimeras…
