First of all, look over my image segmentation demo. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 Then look at how I filter out coins based on size. You need to do the same thing. If they overlap the size will be a lot bigger than if they don't overlap. So you just need to tweak the area value in my code and it should work for you.

See my comment immediately above. In general, I think it will be easier to count all cells (overlapped and non-overlapped alike), and remove the overlapping ones.
To identify the overlapping ones, you can (as Image Analyst stated) use an area criterion, removing all identified cells that exceed some threshold area. In my code above, I showed you how to visualize the areas of the various regions. I'll let you implement the logic about how to identify the overlapping cells.
