Recent advances in laser microprobe mass analysis of inner ear tissue

, : Recent advances in laser microprobe mass analysis of inner ear tissue. Scanning Electron Microscopy (1): 393-406

Maintenance of ionic gradients within the various fluids compartments of the inner ear requires transport active cellular systems at different locations. LAMMA [laser microphobe mass analyzer] analysis is ideally suited for detection of ions in microquantity on cellular levels overcoming many technical difficulties. This paper summarizes the results of microprobe analysis obtained with LAMMA supplemented by X-ray microprobe adjacent to the endolymphatic space (a) in the cochlear duct, in the vestibular organ and in the endolymphatic sac. The possible role of inner ear and ocular melanin in the mechanisms of active ion transport is discussed.

HLA-matched UC blood-derived multipotent stem cells were directly transplanted into the injured spinal cord site of a 37-year-old female patient suffering from spinal cord injury (SPI). In this case, human cord blood (UCB)-derived multipotent stem...
