Author(s):
Shibashish Giri and Augustinus Bader Pages 692 - 705 ( 14 )
Abstract:
Regeneration of diseased organ is a ubiquitous clinical need. The clinical utilities of adult stem cells and microRNA have become a promising strategy for treatment of a number disease. This review aims to highlight the current clinical evidence of personalized and regenerative therapy for diseases like liver which could revolutionize patient care in the near future at a global scale. Herein, we explain the importance of personalized and regenerative medicine for bedside (intraoperative) in situ and In vivo regeneration of damaged organ/ tissues that is now being transferred to a larger field of clinical applications in a novel translational approach.

Abstract:
Liver is a major metabolic organ of the body
and is known to comprise of two epithelial cell lineages, namely, hepatocytes
and cholangiocytes which are known to originate from hepatoblasts during fetal
developing stages. Upon acute injury, the hepatocytes and cholangiocytes
undergo cellular division to compensate the loss, however, chronic damage may
suppress this proliferative ability and as a consequence hepatic and
extra-hepatic stem cells may contribute for liver regeneration. Facultative
liver stem cells (oval cells) may emerge, proliferate and contribute in
replacing damaged hepatic cells. Similarly, bone marrow and mesenchymal stem
cells are also known for contributing in liver regeneration having their
ability of self renewal and differentiation. However, a closer look is still
required to bridge the existing knowledge gaps between functionality and
limitations. Thereby, we have discussed the detailed mechanistic insights of
both hepatic and extra-hepatic stem cells including, stem/progenitor cells, adult/fetal
hepatocytes, oval cells, bone marrow and mesenchymal stem cells. We have also
focused on few in vitro and in vivo studies elucidating therapeutic
applications and challenges related to the liver stem cells. We believe that
such conversations may provide invaluable contribution for realistic
advancement in the state of therapeutic stem-cell transplantation.

Amniotic Membrane Transplant for Articular Cartilage Repair: An Experimental Study in Sheep
Author(s): Diego Garcia, Umile Giuseppe Longo, Javier Vaquero, Francisco Forriol, Mattia Loppini, Wasim S. Khan and Vincenzo Denaro
Affiliation: University Campus Bio- Medico of Rome, Italy.
AbstractPurpose: The aim of the present study was to compare the potential for cartilage repair of fresh amniotic membrane (AM), cryopreserved AM and cryopreserved AM previously cultured with bone marrow mesenchymal stem cells (BM-MSCs) in an in vivo sheep animal model. Methods: A full-thickness cartilage defect was surgically produced in 12 adult sheep, in the bearing region of the lateral femoral condyle. The animals were randomized into 4 groups (n=3): no treatment of the defect (G1); filling with fresh AM (G2); with cryopreserved AM previously cultivated with BM-MSCs (G3); with cryopreserved AM alone (G4). Postoperatively, the full load was possible. At two months, the animals were euthanized. The quality of the new synthesized tissue was evaluated with the macroscopic, by using International Cartilage Repair Society (ICRS) scale, and histological analyses, by using O’Driscoll scale. Results: The control samples showed an ICRS grade III (abnormal); while the samples of Groups 2, 3 and 4 reported a grade II (similar to healthy cartilage). The mean value of O’Driscoll scale in the control group (3.3) was significantly lower compared to the treatment groups (G2: 10.7; G3: 8; G4: 11.3) (P <0.05). No significant differences were found between the experimental groups. Conclusion: AM could be a suitable material for the management of articular cartilage defects. Stem cells within AM demonstrated to be able to differentiate in chondrocytes in vivo. Fresh AM, cryopreserved AM and cryopreserved AM previously cultivated with BM-MSCs showed similar regenerative properties.

Abstract
Larynx cancer (LCa) is an aggressive malignancy, which is the second most common malignant neoplasm of head and neck squamous cell carcinoma. Its incidences have been reported to increase and therapeutic options mostly fail to give positive clinical response especially for the advanced LCa cases. In this study we aimed to isolate stem-like cells from freshly resected LCa tumor specimens and characterize them by quantitative real time PCR (qRT-PCR) for expression of cancer stem cell markers including SOX2, OCT4, KLF4, ABCG2, CXCR4 and CD44. Our results showed that CD133(high) cells directly isolated from freshly resected tumor specimens exhibit elevated levels of SOX2, OCT4 and KLF4, and have increased expression levels of ABCG2 and CXCR4, which were associated with resistance of tumors to regular chemotherapeutic reagents. In conclusion, this study offers a useful approach utilizing CD133 to isolate stem cells directly from fresh tissues, which gives the opportunity to develop novel therapeutic tools specifically targeting these cells through their further characterization.
Spleen Stroma Maintains Progenitors and Supports Long-Term Hematopoiesis

Abstract
Hematopoietic stem/progenitor cells (HSPC) differentiate in the context of stromal niches producing cells of multiple lineages. Limited success has been achieved in the past with induction of hematopoiesis in vitro. Previously, spleen long-term stromal cultures (LTC) were shown to continuously support restricted hematopoiesis for production of novel dendritic-like cells (LTC-DC). An in vivo equivalent dendritic cell type was then described which is specific for spleen. The in vivo counterpart cell was termed ‘L-DC’ and represents a dendritic-like CD11cloCD11bhiCD8α-MHC-II- cell which differs phenotypically and functionally from monocytes/macrophages and conventional and plasmacytoid DC. Splenic stroma is now shown to maintain HSPC and to support their restricted in vitro differentiation to give this ‘L-DC’ subset. In order to characterise progenitors of this distinct cell type, LTC were analysed for cell subsets produced, and these subsets sorted and assessed for hematopoietic potential in subsequent co-cultures over STX3 stroma. Progenitors were defined as a lineage (Lin)–ckitlo subset reflecting HSPC. Furthermore, when Lin–ckithiSca1+Flt3– HSPC were sorted from bone marrow, they colonised splenic stroma with long-term production of L-DC. The maintenance of HSPC by splenic stroma was confirmed when non-adherent cells collected from LTC showed oligopotent reconstitution of the hematopoietic compartment of lethally irradiated mice. All data support a model whereby spleen houses a niche for HSPC in the resting state, with production of progenitors, and their differentiation to give tissue-specific antigen presenting cells.
