Abstract:The present findings evidenced the superior quality of smaller caprine islets compared to larger ones under an optimized basal maintenance condition. As it is equally important to preserve the quality of larger caprine islets, this work warrants further investigation on special culture conditions to support these islets.
“…Detail studies on adaptation of orf virus in tissue culture and embryonating eggs would pave the way for further studies to elucidate orf virus biology, mechanisms and preparation of the virus for vaccines to control and eradicate the disease Sadiq et al, 2017;Bala et al, 2018). It would be rather intriguing to determine the capability of orf virus to grow in cell lines of the original host perhaps to affect cell growth in vitroas well (Vakhshiteh et al, 2013;Hani et al, 2010). Besides parapoxviruses, herpesvirus family also portraying similar characteristics to grow in cell lines PCR and viral isolation were employed as confirmatory diagnosis for diseases.…”

Section: Maintenance Of Caprine Islets In Media With Various Supplementioning
Background
Dead islets replaced with viable islets are a promising offer to restore normal insulin production to a person with diabetes. The main reason for establishing a new islet source for transplantation is the insufficiency of human donor pancreas while using xenogeneic islets perhaps assists this problem. The expression of PDX1 is essential for the pancreas expansion. In mature β‐cells, PDX1 has several critical roles such as glucose sensing, insulin synthesis, and insulin secretion. In this study, we aimed to evaluate the expression of pancreatic duodenal homeobox‐1 (PDX1) in treated caprine islets in culture and to assess the protective effects of antioxidant factors on the PDX1 gene in cultured caprine islets.
Materials and methods
Purified islets were treated with serum‐free, serum, IBMX, tocopherol, or IBMX and tocopherol media. Quantitative polymerase chain reaction and Western blotting were carried out to compare the expression levels of PDX1 in treated purified islets cultured with different media.
Results
Islets treated with IBMX/tocopherol exhibited the highest fold change in the relative expression of PDX1 on day 5 post‐treatment (relative expression: 6.80±2.08), whereas serum‐treated islets showed the lowest fold changes in PDX1 expression on day 5 post‐treatment (0.67±0.36), as compared with the expression on day 1 post‐treatment. Insulin production and viability tests of purified islets showed superiority of islet at supplemented serum‐free media with IBMX/tocopherol compared to other cultures (53.875%±1.59%).
Conclusions
Our results indicated that supplemented serum‐free medium with tocopherol and IBMX enhances viability and PDX1 gene expression compared to serum‐added and serum‐free media.
“…Vakhshiteh et al. examined the viability and insulin secretion of caprine islets in vitro . Caprine islet had a diameter between 50 and 250 μm, in which 80% of the total islet yield was defined as small islets with a diameter of ≤150 μm.…”
