Background: Cytokines and growth factors were reported to play an important role in stimulating fibroblast proliferation. In vitro culture, fibroblast is mostly culture in medium containing fetal bovine serum (FBS).  Human umbilical cord blood (hUCB) has been reported to have low immunogenic property and potential in wound healing, so therefore hUCB serum (hUCBS) could be potential and were investigated in current study.Materials and Methods: Five hUCBs were collected from healthy volunteers with normal delivering procedure. hUCB was ex utero immediately collected from umbilical vein in vacutainers and processed. NIH3T3 cells were cultured in DMEM with 10% FBS or 5-20% hUCBS for 48 hours. Cells were then quantified using MTT assay. Protein concentration of FBS and hUCBS were quantified using Bradford assay.Results: NIH3T3 cells density grown in DMEM with 10% FBS was the lowest. NIH3T3 cells densities were increased along with the increment of hUCBS concentrations. MTT results showed that average number of NIH3T3 cells grown in DMEM with 10% FBS was 6,185±1,243. Meanwhile average numbers of NIH3T3 cells grown in DMEM with 5%, 10% and 20% hUCBS were 8,126±628, 9,685±313 and 12,200±304, respectively. Average numbers of NIH3T3 cells grown in DMEM with 5% hUCBS were significantly higher than the ones with 10% FBS (p=0.000). Bradford results showed that concentration of hUCBS was significantly higher than the one of FBS (p=0.000).Conclusion: hUCBS could induce higher proliferation rate of NIH3T3 cells than FBS. Hence hUCBS could be suggested as an alternate of FBS in inducing fibroblast.Keywords: NIH3T3, fibroblast, UCB, serum, FBS, proliferation

This study investigated the use of bovine serum albumin (BSA) plus insulin–transferrin–sodium selenite (ITS) and/or epidermal growth factor (EGF) as alternatives to fetal bovine serum (FBS) in embryo culture medium. The developmental ability and quality of bovine embryos were determined by assessing their cell number, lipid content, gene expression and cryotolerance, as well as the invasion ability of trophoblasts. The percentage of embryos that underwent cleavage and formed a blastocyst was higher (P<0.01) in medium containing ITS plus EGF and BSA than in medium containing FBS. Culture with ITS plus EGF and BSA also increased the hatching ability of blastocysts and the total cell number per blastocyst. Furthermore, the beneficial effects of BAS plus ITS and EGF on embryos were associated with a significantly reduced intracellular lipid content, which increased their cryotolerance. An invasion assay confirmed that culture with ITS plus EGF and BSA significantly improved the invasion ability of trophoblasts. Real-time quantitative polymerase chain reaction analysis showed that the mRNA levels of matrix metalloproteinase-2 (MMP2) and MMP9, acyl-CoA synthetase long-chain family member 3, acyl-coenzyme A dehydrogenase long-chain and hydroxymethylglutaryl-CoA reductase significantly increased upon culture with ITS plus EGF and BSA. Moreover, protein expression levels of matrix metalloproteinase-2 and -9 increased (P<0.01) in medium supplemented with ITS plus EGF and BSA compared with medium supplemented with FBS. Taken together, these data suggest that supplementation of medium with ITS plus EGF and BSA improves invitro bovine embryo production, cryotolerance and invasion ability of trophoblasts.

Safety concerns over cell-derived pharmaceutical products being manufactured in supplements of fetal bovine serum (FBS) have ignited pleas to replace FBS. Herein, four newly marketed alternatives to FBS were compared: a xeno-free product called Cell-Ess®, a human platelet lysate marketed as GroPro®, and two mixtures of adult bovine serum varying in their proportions of neonatal growth factors, called Liporo® and FetalGro®. An endothelial cell line (C2BBe1) and a neuronal cell line (SHSY5Y) near confluency in media with 10% FBS were selectively scraped and taken through a 25-day step-wise algorithm to replace FBS, and another human endothelial cell line (HRA-19) was studied to replicate C2BBe1. Cells were stained, counted, and compared for viability, migration, and spheroids. The C2BBe1 and HRA-19 cell lines failed to proliferate in 10% Cell-Ess® but grew in 10% GroPro® or 10% FetalGro® reasonably well compared to reference 10% FBS. With SH-SY5Y, only FetalGro® approached FBS's efficacy. These were all inferior to 11 different branded lots of FBS (positive controls), but five days into switching just amongst the FBS brands, 4 of 11 supported less proliferation than reference FBS in endothelial HRA-19 ( p < 0.004). Moreover, neurospheres were enriched in two branded lots of FBS and FetalGro® (each p < 0.004), neurospheres being an unwanted phenotype for any neuronal cell application. Because platelet-derived GroPro® stood out amongst the non-FBS growth supplements to allow proliferation without inducing spheroids, it seems the best (mindful that the cells still grew slower in it compared to FBS). While no perfect replacement was found amongst the alternatives to FBS, the algorithm for switching should be useful in future testing of new alternatives to FBS as the need arises to switch from FBS and expand pharmaceutical products with safety for human use.

Hatching Rates

Porcine embryos, derived from in vitro maturation and fertilization, were used to investigate the effects of timing of serum inclusion and PVA replacement in the medium for in vitro culture (IVC) on rates of blastocyst formation and hatching. In Experiment 1, presumptive zygotes at 20 h post-insemination (hpi) or cleaved embryos obtained by culture in porcine zygote medium (PZM-5) containing 3 mg mL−1 polyvinyl alcohol (PVA) at 48 or 96 hpi were further cultured in either PZM-5 containing PVA or PZM-5 where PVA was replaced by 1%, 5%, or 10% fetal bovine serum (FBS) until Day 6 (Day 0 = the day of in vitro insemination). Supplementation with 1% to 10% FBS at 20 and 48 hpi reduced (P < 0.05; by ANOVA and Fisher's PLSD test) blastocyst rates on Days 5 (0% to 1%) and 6 (3% to 6%) compared with PVA supplementation (4% and 22%, respectively). However, addition of 10% FBS at 96 hpi increased (P < 0.05) blastocyst rates (30%) on Day 5 compared with PVA (11%) and 1% FBS (15%); there was no significant difference among treatments in rates of blastocyst formation on Day 6 (24% to 40%). The total number of blastomeres in Day 6 blastocysts did not differ among treatments at any timing of serum supplementation (26.5 to 48.3 cells). In Experiment 2, presumptive zygotes were cultured from 20 to 96 hpi in PVA medium, and the cleaved embryos were later transferred into PZM-5 containing PVA, or 1%, 5%, or 10% FBS for another 4 days. Hatching rates of embryos on Days 7 and 8 were significantly higher (P < 0.05) in PZM-5 where PVA was replaced with 10% FBS (15% and 20%, respectively) than those in PZM-5 containing PVA (1% and 5%, respectively). Moreover, the total cell number in hatching/hatched blastocysts on Day 8 were significantly greater (P < 0.05) in medium containing 10% FBS (135.1 cells) than that in PVA medium (77.0 cells). In Experiment 3, at 130 hpi, blastocysts derived from IVC with PZM-5 containing PVA were transferred into PZM-5 containing PVA, 3 mg mL−1 bovine serum albumin (BSA) or 10% FBS for another 2 days. Hatching rates of blastocysts on Days 6, 7 and 8 were significantly higher (P < 0.05) in PZM-5 where PVA was replaced with 10% FBS (12%, 56%, and 64%, respectively) than those in PZM-5 containing PVA (0%, 12%, and 20%, respectively) and BSA (0%, 12%, and 20%, respectively). Moreover, the total cell number in hatching/hatched blastocysts on Day 8 were significantly greater (P < 0.05) in medium containing 10% FBS (138.7 cells) than that in PVA (71.7 cells) and BSA medium (70.7 cells). The results indicate that the timing of serum inclusion in the culture medium markedly affects porcine embryo development in vitro and that replacement of PVA with FBS in PZM-5 at 96 hpi or later improves the subsequent development of embryos to the hatching/hatched blastocyst stage.

Создание эффективной унифицированной системы дозревания донорских ооцитов обеспечит повышение результативности инновационных клеточных репродуктивных технологий. В исследовании проведен сравнительный мониторинг показателеймейотического созревания ооцитов коров, созревших в различных системах, дополненных структурными компонентами фолликулов (СКФ стенки фолликулов, клетки гранулезы, белки) и фолликулярной жидкостью,а также потенций к развитию из них доимплантационных эмбрионов. Анализу подверглись ооциты, прокультивированные в следующих системах:среда ТС199 с добавлением 10 фетальной бычьей сыворотки (ФБС), 50 мкг/мл эстрадиола, 10 мкг/мл лютеинизирующего гормона (ЛГ), 10 мкг/мл фолликулостимулирующего гормона (ФСГ) среда ТС199 с 10 эстральной сывороткой коров среда ТС199 с 50 жидкости из фолликулов диаметром 9 мм среда ТС199 с добавлением белков фолликулярной жидкости молекулярной массой 65 кДасреда ТС199 с 10 ФБС и 1106 клеток гранулезы среда ТС199 с 10 ФБС и тканью фолликула. В культуральные среды ко всем исследованным группам ооцитов добавляли антибиотики. Использование CКФ обеспечило значительное снижение доли ооцитов с дегенерированным хроматином, что способствовало увеличению уровня доимпланационных эмбрионов на стадии бластоцисты. Так, доля бластоцист, развившихся из ооцитов, созревших в среде со стенками фолликулов,составила43,5. В этой же группе выявлен минимальный уровень дегенерированных зародышей (6,45). Полученные данные предлагается использовать при моделировании систем дозревания ооцитов коров с целью повышения качества яйцеклеток.The creation of an effective unified maturation system of donor oocytes provides an increase in the efficiency of innovative cellular reproductive technologies. The comparative analysis of the meiotic maturation indicators of bovine oocytes, which were matured in different cultural systems modified by follicular structural components (FSC follicular walls, granulosa cells, proteins) and follicular fluid, as well as the potential for preimplantation embryonic development were evaluated in this study. Oocytes matured in following cultural systems: medium TC199 supplemented with 10 fetal bovine serum and 50 g/ml of estradiol, 10 g/ml of luteinizing hormone (LH), 10 g/ml of folliclestimulating hormone (FSH) medium TC199 with 10 estrous cow serum medium TC199 with 50 liquid from follicles with a diameter of 9 mm medium TC199 supplemented with the follicular fluid proteins with molecular weight 65 kDa medium TC199 with 10 fetal bovine serum and 1106 granulosa cells medium TC199 with the addition of 10 fetal bovine serum and follicle tissues were analyzed. Antibiotics were added to cultural media of all experimental groups of oocytes. The usage of FSC ensured the decrease in the proportion of oocytes with degenerated chromatin, which contribute the rise of the level of preimplantation embryos at the blastocyst stage. Thus, the proportion of blastocysts developed from oocytes matured in medium supplemented with follicular walls was 43.5. In the same experimental group, the number of degenerated embryos was 6.45. The obtained data are supposed to be used for modeling the cultural systems of cow oocytes in order to improve the egg quality.
