I believe lyososomes aid the function of cell renewal within the liver by digesting cellular components to recycle back for renewal.
One of the function of lysosomes is the renewal of cells and organelles; They cause the breakdown of ageing and worn out dead cells to make their component molecules available for the formation of new cells and organelles. Other functions includes; extracellular digestion, intracellular digestion, sperm penetration among other functions.
