Beneficial Effects of Low Frequency Vibration on Human Chondrocytes in Vitro.

Background/aims: In articular cartilage, chondrocytes are the predominant cell type. A long-term stay in space can lead to bone loss and cartilage breakdown. Due to the poor regenerative capacity of cartilage, this may impair the crewmembers' mobility and influence mission activities.

Pathway Analysis Hints Towards Beneficial Effects of Long-Term Vibration on Human Chondrocytes.

Background/aims: Spaceflight negatively influences the function of cartilage tissue in vivo. In vitro human chondrocytes exhibit an altered gene expression of inflammation markers after a two-hour exposure to vibration. Little is known about the impact of long-term vibration on chondrocytes.
