Heat Map Cell values display

I noticed the cell values are displayed with arbitrary size and with 'normal' fontweight.

I wonder whether one can choose, the font, and fontweight for the diplayed values on each cell.

The imagesc demo in this answer produces a plot nearly identical to a heatmap and the last line allows you for format the cell labels.

Example of setting cell labels (adaptation of the last line from that answer),

th = text(xTxt(:), yTxt(:), labels(:), ...
    'VerticalAlignment', 'middle','HorizontalAlignment','Center',...
    'FontSize', 12, 'FontWeight','bold','Color','g');
