One of those little coloured diagrams reminds me somewhat of the rectangle pattern illustrating the Fibonacci sequence. So leaving aside individual cell shape for the moment, do any cells proliferate by division in accordance with Fibonacci? If they do, it could be like this:

Hour 1 1 cell
Hour 2 1 cell
Hour 3 The cell divides into 2
Hour 4 Just one of those 2 cells divides again into 2, the other does nothing. So 3 cells.
Hour 5 The one that did nothing in the pevious hour now divides into 2, as does one of the other 2, while the remaining one does nothing, so 5 cells.

I won't try and go on verbally, but you can set out these and subsequent generations using a dot for one cell, followed by either two relatively closely spaced dots just underneath it in the next line to represent a split into two cells, or only one dot for a do nothing. It's not only easier and more revelatory than visualising pairs upon pairs of rabbits, but maybe more realisitic too, even if we can't just now say what would cause a proportion converging on approx 0.618 of cells in each generation to refrain from dividing to produce issue in the next. But differential division rates in different layers of the same cell type could result in preprogrammed tissue buckling for example. And as I pointed out in a comment to Rachel's "Brief introduction to the Fibonacci sequence", there's a companion self-additive sequence known as "Narayana's Cows" with an even more lumbering gait and longer do nothing time, so maybe each has its own effect on tissue geometry.
