SIS has been obtained from various sources and processed in different ways, thereby making it difficult to determine the single most important factor in obtaining reliable and consistent bladder regeneration using the unseeded technique.
Hepatocytes showed variation in cell and nuclear size, and varying plate width, consistent with regeneration on reticulin stain (Fig. 2E).
Fourteen days p.i. normal architecture of the lung was restored in animals from these groups, apart from some residual peribronchiolar lymphocytic infiltrate and mild hyperplasia and hypertrophy of the bronchiolar and alveolar epithelium, consistent with regeneration.
Liver biopsy demonstrated hepatocytes with mild variation in nuclear size, mild hepatocellular iron accumulation in a pericanalicular pattern (Fig. 2J), and several zones displaying abnormally widened hepatocyte plates, consistent with regeneration (Fig. 2K).
Alternatively, and consistent with regeneration experiments in vivo, PPAR γ2 restoration resulted in a 15% increase in PPAR γ+ cells as well as a 15% increase in Ck14+ cells, quantified in Figure 2c).
Consistent bone regeneration for the treatment of combined vertical and horizontal defects without the application of large bone grafts, exogenous growth factors, or cells still remains a challenge for clinicians and surgeons.
By contrast, most tropical and temperate populations conformed to a negative exponential distribution, consistent with frequent regeneration.
Interestingly, the kinetics of the resolution of the vacuolization is consistent with rapid regeneration of bronchiolar epithelium.
