ABSTRACT

BACKGROUND:

Although bone marrow mesenchymal stem cels from multiple myeloma patients present a variety of abnormalities, it is unclear how these abnormal mesenchymal stem cels influence the chemotactic function of myeloma cel lines.

OBJECTIVE:

To investigate thein vitro effects of bone marrow mesenchymal stem cels from normal donors versus multiple myeloma patients on the chemotactic capacity of myeloma cel lines.

METHODS:

In vitro cultured bone marrow mesenchymal stem cels derived from either normal donors (N-MSCs group) or newly-diagnosed multiple myeloma patients (MN-MSCs group) were directly co-cultured with U266 cels, in the presence or absence of bortezomib; and then harvested U266 cels were assayed for Transwel migration and mRAN expression of chemotaxis-related genes. U266 Transwel migration to conditioned medium derived from either N-MSCs or MN-MSCs was also tested. RESULTS AND

CONCLUSION:

After co-cultured with N-MSCs or MN-MSCs, U266 cels harvested from MN-MSCs group showed increased spontaneous Transwel migration and up-regulated CCR1 mRNA level than those from N-MSCs group (P < 0.05), whatever bortezomib was present or not. However, there was no evident difference between U266 cel Transwel migration to conditioned medium derived from either MM-MSCs group or N-MSCs group. Our study implies that there may be some intrinsic aberrance in bone marrow mesenchymal stem cels derived from multiple myeloma patients, which can modulate the chemotactic migration of myeloma cel lines when they directly interact with each other.
