What is the main advantage of this dissection technique?
The main advantage is its speed and standardization, allowing for quick and reproducible results.
How long does the procedure take?
The entire procedure can be completed in about seven minutes when performed correctly.
What applications can the isolated bone marrow be used for?
The isolated bone marrow is suitable for various analyses, including histomorphometry and cell culture.
Is the procedure sterile?
Yes, the bone marrow isolation procedure is designed to be fairly sterile.
What should be done if the tibial epiphysis is intact?
If the tibial epiphysis is intact, scissors should be guided up the tibia shaft to remove the condyles and epiphysis.
Can this technique be used for other types of analyses?
Yes, after isolation, other methods like FACS can be performed to study bone marrow cell populations.
