Is Bone marrow solid or liquid in form...
« on: 29/07/2008 05:57:26 »
I ask because My Daughter has started me to buying

these huge bones for my dog to chew on and I understand

they are big leg portions of a cow which they remove from

the Joints.. so each end has this huge joint on it...

(and I don't mean weed!!!)

The dogs love them, especially when they get into the bones middle

to the marrow!


Now I see as the cow is obviously dead and

butchered, that this marrow inside is very hard,.... not quite

as hard as the bone, but is that because the cow is dead.. Or

is bone marrow solid..?


I have always assumed without really

knowing that it was liquid when the critter was living, as I

would also assume it is liquid for humans when we are living too, but is it???

Is it a thick like fluid...or what, and what color is it?


Please do tell if you know???

Wow Thats cool! I did not know that and my assumption was way off.. Thank you RD!

Can you tell me kinda what the procedure is for bone marrow transplants ? How do they remove the doner marrow? Does the doner's marrow resupply itself with new marrow?

Bone marrow stem cells are collected from the donor either by bone marrow tap (drilling a hole into the marrow cavity and sucking the stem cells out), or less painfully by giving a drug called G-CSF, which causes the stem cells to increase their rate of cell division so that they begin to spill out into the blood stream; this means that they can be harvested from peripheral blood.

The spongy bone will be broken up by the large needle when the marrow is sucked out, (harvested).
I think the bone marrow stem cells are then separated out from the tiny bone fragments using a centrifuge.
