Diameter distributions in each adipocyte preparation were determined as reported by digital analysis of suspended cells using a Nikon Eclipse 80i microscope and Nikon Digital DXM 1200C camera. Digital images were analyzed using Nikon NIS-Elements (NE) Br software, generating mean diameters (with distribution), in micrometers (μ), for each preparation. The mean cell surface area and cell volume, in μ2 and pl, respectively, were computed from the diameters 20 (link), 21 (link).
