Hematopoiesis occurs in the bone marrow, where primitive hematopoietic cells proliferate and differentiate in close association with a three-dimensional (3D) hematopoietic microenvironment composed of stromal cells. We examined the hematopoietic supportive ability of stromal cells in a 3D culture system using polymer particles with grafted epoxy polymer chains. Umbilical cord blood-derived CD34+ cells were co-cultivated with MS-5 stromal cells. They formed a 3D structure in the culture dish in the presence of particles, and the total numbers of cells and the numbers of hematopoietic progenitor cells, including colony-forming unit (CFU)-Mix, CFU-granulocyte-macrophage, CFU-megakaryocyte and burst-forming unit-erythroid, were measured every seven days. The hematopoietic supportive activity of the 3D culture containing polymer particles and stromal cells was superior to that of 2D culture, and allowed the expansion and maintenance of hematopoietic progenitor cells for more than 12 weeks. Various types of hematopoietic cells, including granulocytes, macrophages and megakaryocytes at different maturation stages, appeared in the 3D culture, suggesting that the CD34+ cells were able to differentiate into a range of blood cell types. Morphological examination showed that MS-5 stromal cells grew on the surface of the particles and bridged the gaps between them to form a 3D structure. Hematopoietic cells slipped into the 3D layer and proliferated within it, relying on the presence of the MS-5 cells. These results suggest that this 3D culture system using polymer particles reproduced the hematopoietic phenomenon in vitro, and might thus provide a new tool for investigating hematopoietic stem cell–stromal cell interactions.

Innovations in in vitro ovarian follicle culture have revolutionized the field of fertility preservation, but the successful culturing of isolated primary and small secondary follicles remains difficult. Herein, we describe a revised 3D culture system that uses a feeder layer of ovarian stromal cells to support early follicle development. This culture system allows significantly improved primary and early secondary follicle growth and survival. The stromal cells, consisting mostly of thecal cells and ovarian macrophages, recapitulate the in vivo conditions of these small follicles and increase the production of androgens and cytokines missing from stromal cell-free culture conditions. These results demonstrate that small follicles have a stage-specific reliance on the ovarian environment, and that growth and survival can be improved in vitro through a milieu created by pre-pubertal ovarian stromal cell co-culture.

Abstract We have constructed a biomimetic hematopoietic niche (3D culture system) with bio-derived bone as framework, composited with human marrow mesenchymal stem cells, and induced the cells into osteoblasts. Our primary results showed that the biomimetic 3D culture system is capable to allow maintenance and expansion of primitive hematopoietic progenitor cells in vitro. But so far, leukemia primary cells long-term culture from patients marrow are still difficult because it is not clear how does the regulation of leukemic cells grow ex vivo, and lack of adequate investigation between leukemic stem cells with stromal cells. Based on our previous research, we cultured bone marrow mesenchymal stem cells from chronic myelogenous leukemia (CML) patients, and conceived a “pathologic biomimetic osteoblast niche”, to explore the growth of leukemia bone marrow primary cells from CML patients. Bio-derived bone was composited with marrow mesenchymal stem cells from CML patients and constructed a 3D biomimetic osteoblast niche. The mononuclear cells (MNCs) were collected with standard Ficoll-Paque separation from newly diagnosed CML patients. The MNCs were cultured for 2∼5 weeks in the 3D culture system and compared with 2D culture system. The results showed that the proportion of CD34+ cells are increased either in 3D or 2D culture systems. Compared to input, the proportion of CD34+ cells were increased 6.52(1.87∼9)vs. 3.18(1.07∼6.8)times at 2 weeks culture, and 13.6(3.59∼26.31)vs. 7.86(0.78∼18.0)times at 5 weeks culture. The proportion of CD34+/CD38- was higher in 3D culture system than 2D system. It was 5.55(2.1∼11.7)% vs. 2.4(0.9∼3.4)%, and 13.5(3.4∼34.2)% vs. 4.83(2.1∼8.9)% at 2 weeks and 5 weeks respectively. The function of cultured cells was evaluated in colony forming unit (CFU) assay and long term culture initial cell (LTC-IC) assay. 3D system produced more colonies than 2D system {103.33(82∼144)vs. 79(53∼122)} at 2 week culture and 47(33∼66)vs. 21.67(16∼27)at 5 week culture. LTC-IC are widely used as a surrogate in vitro culture for pluripotent stem cells, and those primitive progenitor cells responsible for leukemia in mice are named SL-IC or leukemia stem cells (LSCs). 3D system showed higher frequency of LTC-IC than that of 2D system after 2-week culture(2.23E-05(1.73∼2.56)vs.1.40E-05(1.21∼1.73)). FISH showed the proportion of Ph+ cells declined in both system during the culture, but not as rapidly as it did in 2D system{65%(3D)vs.63%(2D)at 2 week, 55%(3D)vs.35%(2D)at 5 week}, and the Ph+ cells were predominant derived from 3D culture. Our 3D culture system constructed with induced osteoblasts from mesnchymal stem cells in CML patients might provide a more suitable microenvironment for leukemic cells growing in vitro. The leukemic stem cells seemed to be regulated by the molecular signals mediated by osteoblast, and the biological characteristics of leukemia stem cells at least partially is maintained. It may be become a new method for studying leukemic HSCs/HPCs behavior in vitro.
