Skeletal Muscle Stem Cells

Skeletal muscle satellite cells (myoblasts) are the primary stem cells of skeletal muscle which contribute to growth, maintenance, and repair of the muscles. Satellite cells are the first stem cells used for cellular cardiomyoplasty more than 20 years ago. The isolation, culture, labeli ...

Cellular Cardiomyoplasty: Its Past, Present, and Future

Cellular cardiomyoplasty is a cell therapy using stem cells or progenitor cells for myocardial regeneration to improve cardiac function and mitigate heart failure. Since we first published cellular cardiomyoplasty in 1989, this procedure became the innovative method to treat dam ...

Clinical Study Using Adipose-Derived Mesenchymal-Like Stem Cells in Acute Myocardial Infarction and Heart Failure

Adipose tissue represents an abundant, accessible source of regenerative cells that can be easily obtained in sufficient amount for therapy. Adipose-derived regenerative cells (ADRC) are comprised of leukocytes, smooth muscles, endothelial cells, and mesenchymal stem cells. In ...

Clinical Trials of Cardiac Repair with Adult Bone Marrow- Derived Cells

The past decade has witnessed a marked increase in the number of clinical trials of cardiac repair with adult bone marrow cells (BMCs). These trials included patients with acute myocardial infarction (MI) as well as chronic ischemic heart disease (IHD) and utilized different types of BMCs with v ...

Decellularized Whole Heart for Bioartificial Heart

Whole-organ decellularization has opened the gates to the creation of 3D extracellular matrix (ECM) templates that mimic nature’s design to a degree that—as for today—is not reproducible with any synthetic materials. Here, we describe a whole-heart decellularization approach thro ...

Bio-hybrid Tissue Engineering for Cellular Cardiomyoplasty: Future Directions

Cardiomyopathy induces geometric alteration of the ventricular cavity, which changes from a natural elliptical (conical) to a spherical shape. Ventricular chamber dilatation and spherical deformation are important causes of morbidity and mortality among patients with con ...

Route of Delivery, Cell Retention, and Efficiency of Polymeric Microcapsules in Cellular Cardiomyoplasty

Stem cell transplantation has been considered as a major breakthrough for treating ischemic heart disease. However, survival and retention of transplanted cells at the site of infarction remains tenuous. This chapter details a method of creating polymeric microcapsules for cell de ...

Immune Responses After Mesenchymal Stem Cell Implantation

Stem cell transplantation is a promising approach for improving cardiac function after severe myocardial damage for which use of autologous cells have been preferred to avoid immune rejection. Recently, however, rodent as well as human mesenchymal stromal cells (MSCs) have been repor ...

Cell-Based Assays for Regulators of Tau Biology

Understanding the molecular mechanisms of Alzheimer’s disease (AD) is a challenging endeavor, namely, due to the fact that the disease only occurs in the central nervous system of elderly humans. Thus, model systems simply do not accurately portray this cellular landscape. While we cannot a ...

Detection of APP Intracellular Domain in Brain Tissue

The cleavage of amyloid precursor protein (APP) by γ-secretase produces Aβ peptides, which are prominent features in Alzheimer’s disease and have been extensively studied. By contrast, APP intracellular domain (AICD), also a product of this cleavage event, has received little or no inves ...

Measuring APP Carboxy-Terminal Fragments

The accumulation of the amyloid-β (Aβ) peptide in the form of insoluble fibrillar deposits and soluble oligomeric aggregates is widely believed to play a causal role in Alzheimer’s disease (AD). Proteolytic cleavage of APP by the β-site APP cleaving enzyme (BACE1) near the C-terminus results in ...

Assessing A Aggregation State by Atomic Force Microscopy

There has been a growing recognition of a wide variety of diseases commonly referred to as conformational diseases, which share the feature of specific disease-related proteins adopting nonnative conformation that promote their ordered aggregation and deposition on surfaces. D ...

Detecting undefined56 Oligomers in Brain Tissues

Since its original description in 1906 by Dr Alois Alzheimer, amyloid plaques and neurofibrillary tangles have remained the hypothetical cause of Alzheimer’s disease. However, plaque burden poorly predicts cognitive status in humans, which led several groups to investigate the po ...

Isolation of Low-n Amyloid -Protein Oligomers from Cultured Cells, CSF, and Brain

Recent data suggest that soluble, non-fibrillar assemblies of the amyloid β-protein (Aβ) may mediate the synaptic deficits that characterize the early stages of Alzheimer’s disease. Consequently, much effort has been expended in isolating and studying a variety of different Aβ assem ...

Preparing Synthetic A in Different Aggregation States

This chapter outlines protocols that produce homogenous preparations of oligomeric and fibrillar amyloid-β peptide (Aβ). While there are several isoforms of this peptide, the 42 amino acid form is the focus because of its genetic and pathological link to Alzheimer’s disease (AD). Past dec ...

Apolipoprotein E Expression and Purification

Since the discovery of the association of apolipoprotein E (apoE) 4 with Alzheimer’s disease 17 years ago, numerous in vitro experiments with the apoE isoforms (apoE2, apoE3, and apoE4) have been performed to try to understand the basis for this association. The majority of these studies used com ...

Contemporary Approaches to Alzheimers Disease and Frontotemporal Dementia

Alzheimer’s disease and frontotemporal dementia are two of the most common neurodegenerative dementias. Here, we review the clinical presentation, genetic causes, typical neuropathology, and current treatments for these disorders. We then review molecules involved in their p ...

Manipulation of Gene Expression in the Central Nervous System with Lentiviral Vectors

Viral vector-mediated gene transfer is widely used to manipulate gene expression (overexpression or knock down) in cultures and in different tissues of animals. Vectors based on lentiviruses have particularly useful features. Lentiviral vectors mediate gene transfer into any ne ...

A Toxicity in Primary Cultured Neurons

The aggregation of beta-amyloid (Aβ) into soluble oligomers is considered an early event in Alzheimer’s disease. Furthermore, the presence of these aggregates seems to lead to neurodegeneration in the context of this disease. However, the mechanisms underlying Aβ-induced neurotox ...
