Cell Biology Poster Session

poster 699


Dr. Zador: Hope you are enjoying the meeting.  Great poster.After regeneration in the soleus muscle 98% of the fibers express the slow muscle specific SERCA2a isoforms (these are real slow fibers, also expressing the slow myosin heavy chain isoform). However such fibers are only 81% of total in the normal soleus muscle.  Two questions.  First did the soleus of these rats differ functionally in any way you noticed?  Second, what do you attribute this diffrence to or do you even think that if this experiment were allowed to continue for a long duration, this number would come down to 85%?
