Retinoic acid induces type X collagen expression in cultured chick chondrocytes

A fiche camera is described for exposing frames on a film strip which subsequently is converted to a matrix array of photographic frames on a fiche, and the camera includes a fiche coordinate counting and display device, a shutter for exposing the photographic frames of the film strip, a film transport for advancing the strip film, and camera controls which include a record mechanism that automatically initiate operation of the shutter, the film transport, and the fiche coordinate counting and display device each time the record mechanism is operated. The fiche coordinate counting means visually displays the fiche coordinates of fiche number, column number, and frame number to the operator as documents are recorded.
