Prefa ce
Human hearts have a limited regenerative potential, motivating the development of the
alternative treatment options for the conditions that result in the loss of beating cardio-
myocytes. An example is myocardial infarction that results in a death of tens of millions of
ventricular cardiomyocytes that cannot be replaced by the body. It is estimated that fi ve to
seven million patients live with myocardial infarction in North America alone. A majority of
these patients do not need a surgical intervention, and medical management provides satisfac-
tory results. However, over a period of 5 years, one-half of the patients who experience a
myocardial infarction will develop heart failure, ultimately requiring heart transplantation.
The long-term goal of cardiac tissue engineering is to provide a living, beating, ideally
autologous, and non-immunogenic myocardial patch that can restore the contractile function
of the failing heart. The engineered tissues could also be used for preclinical drug testing to
discover new targets for cardiac therapy and eliminate drugs, cardiac and noncardiac, with
serious side effects. It generally involves a combination of suitable cell types, human or non-
human cardiomyocytes and supporting cells, with an appropriate biomaterial made out of
either synthetic or natural components and cultivation in an environment that reproduces
some of the complexity of the native cardiac environment (e.g., electrical, mechanical stimula-
tion, passive tension, or topographical cues).
This fi eld is still young. The term cardiac tissue engineering usually refers to engineering
of myocardial wall in vitro using living and beating cardiomyocytes. The pioneering papers
appeared in the late 1990s, and they all utilized either neonatal rat cardiomyocytes or
embryonic chick cardiomyocytes as a cell source. Since then, the fi eld has matured signifi -
cantly to include a range of approaches that all give cardiac tissues in vitro that are capable
of developing contractile force and propagating electrical impulses. Advances in human
embryonic stem cell research and induced pluripotent stem cell technology now provide
the possibility of generating millions of bona fi de human cardiomyocytes. When research in
cardiac tissue engineering started some 25 years ago, the issue of a human cell source
appeared insurmountable; however the researchers continued to make way, and there are
many reports now on the use of human pluripotent stem cells as a source of cardiomyocytes
for cardiac tissue engineering. Although early researchers thought that having purifi ed car-
diomyocytes in three-dimensional structures would be benefi cial, based on analogies with
monolayer studies where fi broblasts overgrow cardiomyocytes, there is a consensus in the
fi eld now that a mixed cell population is optimal for maintenance of cardiac phenotype and
survival of cardiomyocytes in engineered tissues both in vitro and in vivo. The mixed popu-
lation usually contains cardiomyocytes, endothelial cells, and a stromal cell type such as
fi broblasts or mesenchymal stem cells. Also, there is a consensus that a form of physical
stimulation, either mechanical or electrical, or passive tension is required for cardiomyo-
cytes to achieve and maintain a differentiated phenotype and in vivo-like functional proper-
ties during in vitro cultivation.
This book gathers for the fi rst time a collection of protocols on cardiac tissue engineering
from pioneering and leading researchers around the globe. Protocols related to cell prepa-
ration, biomaterial preparation, cell seeding, and cultivation in various systems are provided.
v
vi Preface
Our goal is to enable adoption of these protocols in laboratories that are interested in enter-
ing the fi eld as well as enable transfer of knowledge between laboratories that are already in
this fi eld. We hope that these efforts will lead to standardization, defi nition of best practices
in cardiac tissue cultivation, and direct comparison of various production protocols using
controlled in vivo studies that would ultimately lead to translational efforts. Although bio-
material patches alone and hydrogels have been investigated in clinical studies focused on
myocardial regeneration, a cardiac patch based on living, beating human cardiomyocytes
has not yet been tested in humans. Only patches based on non-cardiomyocytes have been
tested in humans with mixed results. Bringing a new therapy to the clinic is an overwhelm-
ing task, one that we must approach in a collaborative rather than competitive spirit. We
hope that sharing of the best protocols in cardiac tissue engineering will enable this goal.
