Abstract
Abstract
Introduction
Seventeen products in five countries are used in medical experiments and clinical trials. FamiCord Group, the leading stem cell bank in Europe and number 3 worldwide, is a listed biotech group consisting of the European biotech companies Vita 34 (Germany), P.B.K.M. (Poland), Crioestaminal (Portugal), Smart Cells (UK), and more than 30 other subsidiaries. FamiCord Group was founded in 2002 and is located in more than 35 countries in Europe and the Middle East. The Group is engaged in the storage of biological material and the manufacture, development, and approval of cell therapeutics for clinical use. More than 850,000 cryopreserved umbilical cord blood and tissue units and more than 4,200 patients treated with stem cells in clinical trials, experimental therapies, and standard therapies demonstrate the extraordinary expertise in stem cell banking and clinical application.
Objective
An overview of the Cell Therapy Pipeline with cell products from the FamiCord Group is shown in Table 1. ATMPs have been developed and manufactured in 3 synergistic R&D centers in Poland, Portugal, and Germany. Twenty preclinical and clinical trials are being conducted as part of in-house and consortia projects.
Methods
Selected new developments are presented in detail: BIOOPA for treatment of epidermolysis bullosa and CartiCure for treatment of cartilage damage in knee joint.
Results
The BIOOPA dressing for the treatment of epidermolysis bullosa is safe and effective, as no infections or necrosis were observed at the graft implant site during the follow-up period. These patients also reported reduced pain and improved quality of life. When used in orthopedics (CartiCure for cartilage damage), cord tissue-derived MSCs have been shown to be safe and fully integrated into the patient's cartilage, resulting in significant improvement in pain scores and quality of life.
Discussion
The trials presented demonstrate that allogeneic cell therapeutics are the future of regenerative medicine. Use of allogenic technology is the only way to overcome the limitations of the autologous approach: manufacturing process extensively scalable, drug available "off the shelf", applicable in all medical facilities, and economical manufacturing process due to unlimited scalability. Large pharmaceutical companies are investing significantly in this space.

Abstract
Processing of MSCs to obtain a therapeutic product consists of two main steps: 1) the in vitro expansion of the cells until an appropriate number of them is obtained, and 2) freezing and storage of the expanded cells. The last step is critical and must be optimized so that after thawing the cells retain all their physiological properties including the secretory function. In this paper, we evaluated physiological parameters of AT-MSC's after a full cycle of their processing, particularly freezing and storing at the liquid nitrogen vapor temperature. Based on the recovered proliferative and secretory capacities of the thawed cells, we have designed the optimal technique for processing of MSCs for clinical applications. In our work, we tried to select the best DMSO-based cryoprotectant mixture on the base of post thawing fully retain their properties. We have demonstrated the effectiveness of the use of DMSO in various configurations of the constituent cryoprotective fluids. We have also shown that AT-MSCs that show control levels in most standard tests (viability, shape, culture behaviour, and proliferative properties) after thawing, may show transient variations in some important physiological properties, such as the level of secreted growth factors. Obtained results let us to indicate how to optimize the AT-MSC preparation process for clinical applications. We suggest that before their clinical application the cells should be cultured for at least one passage to recover their physiological stability and thus assure their optimal therapeutic potential.

Abstract
Mesenchymal stromal/stem cells (MSCs) are a unique population of cells that play an important role in the regeneration potential of the body. MSCs exhibit a characteristic phenotype and are capable of modulating the immune response. MSCs can be isolated from various tissues such as: bone marrow, adipose tissue, placenta, umbilical cord and others. The umbilical cord as a source of MSCs, has strong advantages, such as no-risk procedure of tissue retrieval after birth and easiness of the MSCs isolation. As the umbilical cord (UC) is a complex organ and we decided to evaluate, whether the cells derived from different regions of umbilical cord show similar or distinct properties. In this study we characterized and compared MSCs from three regions of the umbilical cord: Wharton's Jelly (WJ), the perivascular space (PRV) and the umbilical membrane (UCM). The analysis was carried out in terms of morphology, phenotype, immunomodulation potential and secretome. Based on the obtained results, we were able to conclude, that MSCs derived from distinct UC regions differ in their properties. According to our result WJ-MSCs have high and stabile proliferation potential and phenotype, when compare with other MSCs and can be treated as a preferable source of cells for medical application.

Abstract
To optimise the culture conditions for human Wharton's jelly-derived mesenchymal stem cells (hWJ-MSCs) intended for clinical use, we investigated ten different properties of these cells cultured under 21% (atmospheric) and 5% (physiological normoxia) oxygen concentrations. The obtained results indicate that 5% O2 has beneficial effects on the proliferation rate, clonogenicity, and slowdown of senescence of hWJ-MSCs; however, the oxygen level did not have an influence on the cell morphology, immunophenotype, or neuroprotective effect of the hWJ-MSCs. Nonetheless, the potential to differentiate into adipocytes, osteocytes, and chondrocytes was comparable under both oxygen conditions. However, spontaneous differentiation of hWJ-MSCs into neuronal lineages was observed and enhanced under atmospheric oxygen conditions. The cells relied more on mitochondrial respiration than glycolysis, regardless of the oxygen conditions. Based on these results, we can conclude that hWJ-MSCs could be effectively cultured and prepared under both oxygen conditions for cell-based therapy. However, the 5% oxygen level seemed to create a more balanced and appropriate environment for hWJ-MSCs.

Abstract
With the global prevalence of type 2 diabetes mellitus steeply rising, instances of chronic, hard-healing, or non-healing diabetic wounds and ulcers are predicted to increase. The growing understanding of healing and regenerative mechanisms has elucidated critical regulators of this process, including key cellular and humoral components. Despite this, the management and successful treatment of diabetic wounds represents a significant therapeutic challenge. To this end, the development of novel therapies and biological dressings has gained increased interest. Here we review key differences between normal and chronic non-healing diabetic wounds, and elaborate on recent advances in wound healing treatments with a particular focus on biological dressings and their effect on key wound healing pathways.

Abstract
Articular cartilage injuries lead to progressive degeneration of the joint with subsequent progression to osteoarthritis, which currently becomes a serious health and economic issue. Due to limited capability for self-regeneration, cartilage repair remains a challenge for the present-day orthopedics. Currently, available therapeutic methods fail to provide satisfactory results. A search for other strategies that could regenerate a hyaline-like tissue with a durable effect and adequate mechanical properties is underway. Tissue engineering strategies comprise the use of an appropriately chosen scaffold in combination with seeding cells. Mesenchymal stem cells (MSC) provide an interesting new option in regenerative medicine with solid preclinical data and first promising clinical results. They act not only through direct cartilage formation, but also due to paracrine effects, such as releasing trophic factors, anti-inflammatory cytokines, and promoting angiogenesis. The MSC can be applied in an allogeneic setting without eliciting a host immune response. Out of the various available sources, MSC derived from Wharton's jelly of an umbilical cord seem to have many advantages over their counterparts. This article details a novel, single-staged, and minimally invasive technique for cartilage repair that involves dry arthroscopic implantation of scaffold-embedded allogenic mesenchymal stem cells isolated from umbilical cord Wharton's jelly.

Abstract
Transplantation of neural stem/precursor cells has recently been proposed as a promising, albeit still controversial, approach to brain repair. Human umbilical cord blood could be a source of such therapeutic cells, proven beneficial in several preclinical models of stroke. Intracerebroventricular infusion of neutrally committed cord blood-derived cells allows their broad distribution in the CNS, whereas additional labeling with iron oxide nanoparticles (SPIO) enables to follow the fate of engrafted cells by MRI. A 16-month-old child at 7 months after the onset of cardiac arrest-induced global hypoxic/ischemic brain injury, resulting in a permanent vegetative state, was subjected to intracerebroventricular transplantation of the autologous neutrally committed cord blood cells. These cells obtained by 10-day culture in vitro in neurogenic conditions were tagged with SPIO nanoparticles and grafted monthly by three serial injections (12 × 10(6) cells/0.5 ml) into lateral ventricle of the brain. Neural conversion of cord blood cells and superparamagnetic labeling efficiency was confirmed by gene expression, immunocytochemistry, and phantom study. MRI examination revealed the discrete hypointense areas appearing immediately after transplantation in the vicinity of lateral ventricles wall with subsequent lowering of the signal during entire period of observation. The child was followed up for 6 months after the last transplantation and his neurological status slightly but significantly improved. No clinically significant adverse events were noted. This report indicates that intracerebroventricular transplantation of autologous, neutrally committed cord blood cells is a feasible, well tolerated, and safe procedure, at least during 6 months of our observation period. Moreover, a cell-related MRI signal persisted at a wall of lateral ventricle for more than 4 months and could be monitored in transplanted brain hemisphere.

Abstract
Flow cytometric enumeration of CD34+ hematopoietic stem and progenitor cells (HSCs) is widely used for evaluation of graft adequacy of peripheral blood and bone marrow stem cell grafts. In the present study, we review and compare the major counting techniques of stem and progenitor cells. The methods are: the Milan/Mullhouse protocol, two-platform ISHAGE (International Society of Hematotherapy and Graft Engineering) and single-platform ISHAGE analysis system. According to the Milan/Mulhouse protocol, HSCs are identified by CD34 antibody staining and easy gating strategy. The ISHAGE guidelines for detection of CD34+ cells are based on a four-parameter flow cytometry method (CD34PE/CD45PerCP staining, side and forward angle light scatter) thus employing multiparameter gating strategy. With two-platform ISHAGE protocol, an absolute CD34+ count is generated by incorporating the leukocyte count from an automated hematology analyser. The single-platform ISHAGE method to determine the absolute CD34+ count directly from a flow cytometer includes the use of Trucount tubes (Becton Dickinson) with a known number of fluorescent beads. CD34+ cells were quantified in mobilized peripheral blood, collected by leukapheresis, and bone marrow from 42 samples from patients with hematological malignancies. The differences against the means display low disagreement between the Milan/Mulhouse and ISHAGE protocols, with discrepancies of up to 2.5% (two-platform ISHAGE)--2.6% (single-platform ISHAGE) in enumeration of CD34+ cells in leukapheresis product and 4.8% (two-platform ISHAGE)--4.9% (single-platform ISHAGE) in bone marrow. Our results show high correlation among all three methods. Since the three protocols are compatible, choosing the most convenient in terms of costs, simplicity and compliance with clinical results appears to be a logical consequence.

Abstract
Mesenchymal stem cells derived from bone marrow or several fetal tissues can be expanded and differentiated into other cell lines. The fetal liver is the source of early hematopoietic cells and also, as a fetal tissue, may be considered as a source of pluripotent stem cells. The differentiation potential of fetal rat liver cells have been examined. Freshly isolated liver cells from 14-d fetuses were cultured in Dulbecco medium supplemented with 10% FCS. The plastic-adherent cells were then passaged up to 10 times. Freshly isolated cells and cells from every passage were cultured in hematopoiesis-promoting environment that consists of methylcelulose supplemented with FCS, rat IL-3, human IL-6 and Epo. Parallely these cells were incubated in co-culture with rat muscle satellite cells (Dulbecco medium with 10% FCS and 10% HS) to examine their myogenic potential. Culture in methylcelulose resulted in a high number of GM and Mix colonies in case of freshly isolated liver cells and the number of colonies decreased according to the number of passages. In case of cells from 4th passage, there ware no hematopoietic colonies in culture. In contrast--freshly isolated cells were not able to fuse with rat satellite cells and form the myotubes. This ability appeared in plastic-adherent cells just from the second passage and increases to 5th passage. The cells from every next passage up to 10th when co-cultured with satellite cells participated in myotube formation at the same high level. This result may suggest that in the 14-d rat liver there exist at least two subpopulations of cells: the non-adherent hematopoietic cell population, and the population of plastic-adherent cells capable of differentiating into myotubes. Since the attempts to redifferentiate hematopoietic subpopulation into myopoiesis, or myopoietic subpopulation into hematopoiesis failed, it may be concluded that at least under our experimental conditions the fetal liver cells do not reveal the "plasticity" features.

Abstract
The aim of this work was to test the cytotoxicity of newly synthesized cis-type complexes of platinum(II) and palladium(II) dichloride with methyl 3,4-diamine-2,3,4,6-tetradeoxy-alpha-L-lyxohexopyranoside, [M(C(7)H(16)N(2)O(2))Cl(2)].H(2)O, against two mouse lymphoma cell lines (L5178Y) differing in their double strand breaks and nucleotide excision repair ability. cis- Diaminedichloroplatinum (CDDP) was used as a reference compound. The toxicity of Pt(C(7)H(16)N(2)O(2))Cl(2) appeared to be similar for both cell lines: IC(50) is 8 microM for L5178Y-R cells and 12 microM for L5178Y-S cells, respectively. In contrast, the palladium complex was found to be more toxic for the LY-R cells than for the LY-S cells. The cytotoxicity of both compounds was compared with their ability to induce DNA crosslinks, as measured by the modified comet assay. CDDP caused retardation of the DNA migration induced by 2 Gy of the X-irradiation in a dose-dependent manner. The ability of Pd(C(7)H(16)N(2)O(2))Cl(2) to retard X-ray induced DNA migration was more pronounced than its platinum analogue and CDDP (see Fig. 6). However, this was not reflected in the toxicity of the compound. Such results indicate that these two compounds may cause a different type of DNA damage and/or that the DNA damage caused by the palladium(II) compound was dealt with in a different manner from that induced by the platinum(II) complex.

Abstract
The preliminary results of the currently established cord blood bank in Warsaw, Poland have been reported. 163 cord blood samples (mean volume 102 ml) were collected during/or after delivery of the placenta. Average cell numbers per sample were as follows: WBC 13.4 x 10(8); BFU-E 5.7 x 10(4); GM-CFC 4.1 x 10(5); CD34+ 4.5 x 10(6). The quantities and quality of collected cells are suitable for their use for clinical transplantation.
