nervous system
abnormal nervous system regeneration ( J:201118 )
• after optic nerve crush, tamoxifen-treated mice exhibit stronger axonal regeneration compared with control mice though not as complete as in constitutive knock-out mice
• after spinal cord dorsal hemisection injury, tamoxifen-treated mice exhibit improvement of motor function and 5HT fiber density compared with control mice
• however, untreated mice exhibit normal regeneration
