Diminished axonal transport of glycoproteins in the senescent rat brain.

abstract：:The age-related deficit in the dose response of osteoprogenitor cells to IGF-I was further investigated. As expected, the effective dose, but not the maximal effect, was shifted two orders of magnitude higher in old cells. In this paper, we examined whether this age-deficit can be attributed to an alteration in the ex...
