You might try marker controlled watershed segmentation, like in Steve's blog: http://www.mathworks.com/help/images/examples/marker-controlled-watershed-segmentation.html
Or another one of Steve's blogs: http://blogs.mathworks.com/steve/2006/06/02/cell-segmentation/

It looks that the methods in the link, might work also for your image, try to play with the sensitivity of imfindcircles and the tolerance of RemoveOverLap functions.
