There is a number of functions which can be used for region growing, depending on the domain. Please have a look at the following list of Image Processing Toolbox functions, and refer to the linked sections of the MATLAB documentation:

"grayconnected"

"bwmorph" using either the 'dilate' or 'thicken' operations

"imdilate"

"imreconstruct"
