Abstract
Premature ovarian insufficiency (POI) is defined as the development of hypergonadotropic hypogonadism before the age of 40 with definitive treatment being absent. In the current study, we aim to compare the efficacy of the cell sheet method with an intravenous (IV) application of adipose-derived mesenchymal stem cells (AdMSCs) to the POI with an animal model. In the current prospective study, 6-to-8-week-old Sprague Dawley rats were generated four groups: (i) a control group in which only PBS was administered; (ii) an only-POI group generated by cyclophosphamide; (iii) a POI group treated by way of IV AdMSCs; and (iv) a POI group treated by way of the cell sheet method. Twenty-eight days after an oophorectomy was performed, intracardiac blood was taken. Follicle count, immunohistochemical examination for GDF9, BMP15, and TUNEL were conducted, gene expressions of GDF9 and BMP15 were examined, and E2 was measured in the serum samples. With hematoxylin-eosin, in the third group, multi oocytes follicles were the most remarkable finding. In the fourth group, most of the follicles presented normal morphology. GDF9 involvement was similar between the first and fourth groups. BMP-15 immunoreactivity, in contrast to fourth group, was weak in all stages in the second and third groups. The current attempt represents a pioneer study in the literature in which a cell sheet method is used for the first time in a POI model. These results suggest that the cell sheet method may be a feasible and efficient method for the stem cell treatment of models with POI and could be a new treatment approach in POI.

Tuning of Silver Content on the Antibacterial and Biological Properties of Poly(ɛ-caprolactone)/Biphasic Calcium Phosphate 3D-Scaffolds for Bone Tissue Engineering. Polymers (Basel) 2023; 15:3618. [PMID: 37688244 PMCID: PMC10489712 DOI: 10.3390/polym15173618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 08/29/2023] [Accepted: 08/29/2023] [Indexed: 09/10/2023] Open
Abstract
There is a growing interest in tissue engineering, in which biomaterials play a pivotal role in promoting bone regeneration. Furthermore, smart functionalization can provide biomaterials with the additional role of preventing orthopedic infections. Due to the growing microbial resistance to antimicrobials used to treat those infections, metal ions, such as silver, thanks to their known wide range of bactericidal properties, are believed to be promising additives in developing antibacterial biomaterials. In this work, novel poly(ε-caprolactone) (PCL)-based 3D scaffolds have been designed and developed, where the polymer matrix was modified with both silver (Ag), to supply antibacterial behavior, and calcium phosphates (biphasic calcium phosphate, BCP) particles to impart bioactive/bioresorbable properties. The microstructural analysis showed that constructs were characterized by square-shaped macropores, in line with the morphology and size of the templating salts used as pore formers. Degradation tests demonstrated the important role of calcium phosphates in improving PCL hydrophilicity, leading to a higher degradation degree for BCP/PCL composites compared to the neat polymer after 18 days of soaking. The appearance of an inhibition halo around the silver-functionalized PCL scaffolds for assayed microorganisms and a significant (p < 0.05) decrease in both adherent and planktonic bacteria demonstrate the Ag+ release from the 3D constructs. Furthermore, the PCL scaffolds enriched with the lowest silver percentages did not hamper the viability and proliferation of Saos-2 cells. A synergic combination of antimicrobial, osteoproliferative and biodegradable features provided to 3D scaffolds the required potential for bone tissue engineering, beside anti-microbial properties for reduction in prosthetic joints infections.
