What is the most important unmet need in cardiovascular medicine?
The most important unmet need in cardiovascular medicine is that of a regenerative therapy . Although the heart has regenerative capacity, it is limited, and ischemic and other types of cardiac injury leave permanent injury and impairment to heart function which in turn produces major burdens of morbidity, mortality, and healthcare costs. As such, there is major impetus to translate the new knowledge of cardiac stem cell biology to the therapeutic arena (Figure 53.3 ). There have been attempts at cell-based therapy using both cardiopoietic cells – either cardiac stem cells or ESC/iPS strategies – and cells derived from other body sites, most notably bone marrow ( Abdel-Latif et al., 2007 ).
What is the goal of stem cell therapy?
The goal of cellular therapy is to repair damaged tissues by either generation of implantable bioartificial organs or by exogenous stem cells infusion targeting the injured tissue. Once integrated, the cells can either differentiate into the correct tissue-specific cell type to recover the lost function, or recruit and activate resident progenitor cells by means of paracrine mechanisms. Different types of stem cells have been characterized, ranging from pluripotent/multipotent stem cells to partially committed cells such as tissue specific progenitor cells. The extent to which stem cells can be pushed to proliferate or differentiate depend on their origin and developmental stage. Embryonic stem cells (ESCs) and induced pluripotent stem cells (IPSCs) possess the highest differentiation potency. Despite their enormous potential, the direct in vivo application of ESCs has risks associated with potential immunogenicity in humans and teratoma formation. Even though IPSCs are devoid of ethical concerns, they present risks in that they are genetically manipulated. Despite their limited differentiation potential, adult stem cells isolated from several tissues have found wide application in regenerative medicine. Mesenchymal stem cells (MSCs) and amniotic fluid (AF)-derived stem cells have been successfully exploited in preclinical models of acute and chronic kidney injury, together with adipose-derived stem cells (ADSCs) and endothelial progenitor cells.
How do regenerative therapies help with periodontal disease?
Regenerative therapies for periodontal disease that use patients’ cells to repair the periodontal defect have been proposed in a number of preclinical and clinical studies. Periodontal tissue–derived stem cells, such as PDLSCs, are committed toward all of the periodontal developmental lineages that contribute to cell turnover in the steady-state and would thus be useful cell sources for treating periodontally destructive diseases, such as periodontitis. Treatments that partially regenerate damaged periodontal tissue through the localized administration of GFs have now been established. Although the clinical practice is not very successful, such regenerative therapies have provided very useful and feasible clinical study models for the future design of tissue engineering and stem-cell therapies. Using currently available clinical strategies, partial regeneration of the periodontal tissue is becoming possible; however, methods to achieve the functional regeneration of large defects caused by severe periodontal disease are still lacking. To address this, it is essential to better understand the cellular and molecular mechanisms underlying periodontal development and, thereby, identify the appropriate functional molecules that induce the differentiation of stem cells into periodontal lineage cells for the successful reconstruction of periodontal tissue. The field of periodontal bioengineering has entered an exciting new developmental phase that will make increasingly important contributions to the patient. Particularly, a number of biological technologies are being aggressively explored for clinical translation, signifying a veritable “coming of age” of the field. However, such issues as appropriate delivery devices, immunogenicity, autologous cells versus allogenic cells, identifying tissues that provide the most appropriate donor source, control of the whole process, and cost-effectiveness are all important considerations that should not be overlooked. The future of periodontal bioengineering is undoubtedly driven by technology. New applications and improvement upon current designs will depend heavily on innovations in biomaterials engineering. Progress in stem-cell biology will be imperative in dictating advances in stem cell–based regeneration. A better understanding of the molecular mechanisms by which substrate interactions impact stem-cell self-renewal and differentiation is of paramount importance for targeted design of biomaterials. Discoveries in the fields of developmental biology and functional genomics should also be exploited for broadening the repertoire of biological molecules that can be incorporated into biomaterials for fine-tuning stem-cell activities. With the merger between the two powerful disciplines—biomaterials engineering and stem-cell biology—a new drawing board now lies before us to develop therapies that promise to revolutionize periodontal tissue engineering.
What are human induced pluripotent stem cells?
As a source for regenerative therapies, human induced pluripotent stem cells (iPSCs) offer immense potential and was recognized by the 2012 Nobel Committee in Medicine. These cells, derived from differentiated adult cells through genetic reprogramming, have provided an exciting alternative for bypassing ethical concerns related to embryonic stem cells derivation and potential issues of allogeneic immune rejection. Differentiation toward endothelial cells from iPSCs has been extensively studied and reviewed elsewhere. The iPSCs are usually cultured into three-dimensional embryoid bodies in suspension culture followed by differentiation into three germ layers: endoderm, ectoderm, and mesoderm, where endothelial cells belong. Culture strategies including using growth factors, co-culture with parenchymal cells, and 2D culture on coatings enriched with ECM proteins have been used to differentiate ECs from mesodermal cells. For example, inhibition of TGF-β in pluripotent stem cell differentiation increased VE-Cadherin + cells by 10-fold. Subsequent inhibition of TGF-β in culture improved the proliferation of purified endothelial cells up to 36-fold. Co-culture of mouse bone marrow stromal cell line OP9 with iPSCs improved the emergence of CD31 + endothelial cells to as early as 8 days. Transduction of Oct4 and Klf4 into human neonatal fibroblasts in the presence of soluble factors promotes the induction of endothelial reprogramming. Clusters of induced endothelial cells resemble primary human ECs phenotype and protein profiles such as CD31, VE-Cadherin, and vWF were obtained at 28 days.
