use bwareaopen to remove objects smaller than certain number of pixels.
BW2 = bwareaopen(BW, thresh);
[~, numObjects] = bwlabel(BW2,4);

It calculate small and big cells.
I = imread('cell.png');
EDU>> bw = im2bw(I);

Check out for 8-connectivity when using bwlabel or attach your image.
See my code to extract the largest blob, attached below in blue. In there, there is a general purpose function I wrote that can take the N largest or smallest blobs in a binary image.
