Similarly for shRNA infection, Ckit+ enriched bone marrow cells (Automacs technology) where transduced with pLMP-Renilla, pLMP-VprBP, pLMP-DCAF11 or pLMP-DDA1).
Chromosomal analysis (G-banding) was performed on preparations from 48-h bone marrow cell cultures where mitogens were not added, according to a protocol from the American Type Culture Collection.
In this scenario, bone marrow cells migrated to the damaged tubules, where they engrafted and transdifferentiated to make tubule epithelium [56, 57].
However, they did not indicate which bone marrow cells are involved and how and where the new germ cells originate in the recipient.
Where indicated, bone marrow cells were separated (100 ×g, 20 minutes, 20°C) on Percoll (Sigma-Aldrich ref. St . Louis MO) discontinuous gradients (40%/60%/75% isotonic Percoll in medium with 10% FCS).
We have developed a novel 'same day' ex vivo gene therapy strategy in our laboratory, where fresh bone marrow cells are genetically manipulated with a lentiviral vector expressing BMP-2, seeded onto an osteoconductive scaffold, and implanted into the host bone defect in a single sitting without the need to expand these cells in culture [ 69].
Also in human leukemia, high expression of MEIS1 was found in bone marrow cells of acute myelogenous leukemia (AML) patients, where it was always co-expressed with HOXA9 (Smith et al., 1997; Lawrence et al., 1999).
Three recombinant explants, where the cell aggregates consisted of adult bone marrow cells, produced teeth.
However, it is unable to effectively kill CLL cells present in the bone marrow where they reside closely to MSCs and other bone marrow cells.
