Abstract

| Fig. 3 Suppression of salisphere cavitation by chitosan. (a) Illustration showing the in vitro culture system for salispheres with chitosan-coated substrata. (b) Representative phase and sectioned H&E images of salispheres cultured in the control and chitosan groups. (c) Serial sections of a single salisphere to demonstrate cavitation. (d) Representative phase (upper panels) and H&E (lower panels) images of 9-day-old salispheres cultured on chitosan-coated substrata with concentrations ranging from 0.5% to 3% (w/v). (e) Incidence of cavitation at the indicated time-points of culture of control (black-filled dots) and chitosan (Chi, white-filled dots) groups. (f) Quantitative analysis of the incidence of spheroid cavitation. (g) Culture system composed of soluble chitosan. (h) Morphological phenotypes shown in the phase images (upper panels) and sectioned images (H&E, lower panels) of the salispheres cultured by coated chitosan (Chi) and soluble chitosan (ChiM). (i) Quantitation of cavitation in the 9-day-old salispheres cultured with Chi or ChiM. (j) Quantitation of cavitation in the 9-day-old salispheres cultured with control or ChiM. (k) Quantitative analysis of the incidence of spheroid cavitation with different concentrations of soluble chitosan. (l) Representative images of the phase (upper panels) and H&E staining (lower panels) of salispheres cultured with chitosan of different molecular weights. (m) Quantification of the ratios of cavitation in the groups with different molecular weight chitosan (HMW: high molecular weight and LMW: low molecular weight; scale bar = 50 μm in the phase images; b, c and d: scale bar = 100 μm in H&E images; and *p < 0.05; **p < 0.01; ***p < 0.001, t-test.). | ||
