“…It was shown that, even though the elderly group was taken from the brown adipose tissue and had higher MSC expression than in younger persons (30 years old, white adipose tissue), the cardiomyogenesis process was superior when using the cells from younger donors. However, this study cannot maintain a cardiomyogenesis observed in this system after Day 9, as all the interested expressions disappeared [44].…”

“…A study from our group using human adipose MSC taken from a younger donor (30 years old) compared to the elderly donor (60 years old) when co-cultured with h-Cardio on a 3-D scaffold (at 1:5 and 1:6 ratio, respectively), showed that initial culture (Day 2) only the 60 years old group had slight expression of MHC. However, after Day 5, the 30-year old group was superior in expressing cTnT, MHC, ACTN2, and, even, PPARγ, at significantly higher level, but it was diminished after Day 9 in all groups [44]. That study reported that the 1:5 ratio for adipose MSC is superior, as it revealed higher numbers of viable cells.…”

Our study developed a culture system to deliver cells for the regeneration of infarcted myocardial tissue. Human cardiomyocytes (hCardio) and human amnion epithelial stem cells (hAESC) were co-cultured in a biological scaffold forming a 3-D matrix, prepared as a heart patch candidate. The current investigation was aimed for assessment of hCardio-to-hAESC seeding ratio for the best conditions to provide cardiomyogenesis, i.e., 1:5 or the 1:6. This ratio corresponded to optimal cell number of 500,000 cells/cm 2 , thus providing a 12-cm 2 heart patch. This cell ratio was also published in our previous study using human adipose stem cells and hCardio. The hCardio was isolated from the heart tissue taken during surgical correction performed in patients with right ventricular hypertrophy. The cell isolates expressed cTnT (10.7%), cKit/CD117 (16%), ICAM (94%), and PECAM+/VCAM-33%. The hAESC was isolated from an elected donor at Caesarean section. It showed expression of TRA-1-60 (82.4%), SSEA-4 (28.2%), Oct-3/4 (2.9%), Nanog (11.4%), without expression of immune antigens, e.g., HLA-DR (0%), HLA-ABC (0.2%) as well as low-level expression of mesenchymal stem cell (MSC) markers, i.e., CD73 (20.2%), CD90 (0.4%), CD105 (59.2%). These cells did not exhibit Lin phenotype (CD3, CD14, CD16, CD19, CD20, CD56).At both seeding ratios, the co-culture matrix also released TNF-α at low levels (<1 pg/ml) throughout cultivation from day 1 to day 8. Both groups had shown a consistent growth of cells over time. Confocal images showed that the cell population has expanded and migrated to the deeper plane up to 140 µm after 5 days of incubation in both 1:5 and 1:6 groups. The cells seemed to connect and form projections, starting by day 5, being more obvious among the 1:5 group. They proliferated rapidly until no solitary cells were observed after day 8 of co-culture. Expression of the cardiomyogenesis genes, e.g., cTnT and ACTN2 in the 1:6 group were expressed, similarly to normal cardiomyocytes after eight days of cultivation. MHC genes in the 1:6 group were also expressed, although less than 1-fold to normal cardiomyocytes. This study indicated that hCardio and hAESC at 1:6 ratio seeded on amnion bilayer could support cardiomyogenesis derivation from the progenitor cells.
