Figure 2.
Microscopic assessment of morphological structure of PFFs of different sizes. A. Morphological structure of small (s), medium (m) and large (l) cells as assessed by microscopy (10×). B. Phenotype of vacuoles in small (S), medium (M) and large (L) cells as assessed by microscopy (40×); the red arrow refers to the clear vacuoles. C. Quantitative analysis of vacuoles scattered in different sized PFFs. The results are presented as the mean±SD. Data are representative of three independent experiments (a, b, cP<0.05)
