I am culturing human primary fibroblasts obtained from skin punch biopsy, in DMEM +10%FBS+ 1% Ciproflaxin. I see these weird structures floating on the media, however no movement or color change in media observed. The fibroblasts in the plate are growing fine and well adhered to the bottom of the dish(not visible in the magnification layer used to click the following pictures). Is this yeast contamination or clumps of dead cells in the form of debris? Pictures attached are at 4x and 20x magnification.
