11 Tissue Engineering as a Minimally Invasive Method
https://t.me/medicina_free
195
11.5.3 Extracellular Matrix
Derivatives
The extracellular matrix (ECM) is a tissuespecific meshwork of both structural and functional proteins assembled through a process of
dynamic reciprocity whereby cells both receive
signals from the ECM and contribute to its content and organization. This process is critical to
tissue development and homeostasis. Based upon
these important functions, ECM-based materials
have been used in a wide variety of TE/RM
approaches to tissue reconstruction. It has been
demonstrated that ECM-based materials, when
appropriately prepared, can act as inductive templates for constructive remodeling.
An example of ECM derivatives used for
induction of de novo functional, site-appropriate,
tissue formation was shown by Badylak and others in the use of a scaffold material composed of
porcine-derived ECM configured to mimic the
shape and size of the temporomandibular joint
(TMJ) [17]. This device was implanted in a
canine model of bilateral TMJ discectomy. The
results showed that implantation of an initially
acellular material supported the formation of
site-appropriate, functional host tissue that
resembled that of the native TMJ disc.
Furthermore, this prevented gross degenerative
changes in the temporal fossa and mandibular
condyle. The contralateral controls showed no
tissue formation and had mild to severe gross
pathologic changes of the osseous structures of
the joint [17, 18].
11.6 Endoscopic and Arthroscopic
Techniques for Cell Delivery
in TE/RM
The clinical translation of tissue engineering to
minimally invasive therapies is contingent upon
the development of novel noninvasive endoscopic
and arthroscopic techniques. Bioscaffolds can be
delivered on their own as pure cell homing
devices, or they can be pre-seeded with cells that
can assist in the regenerative process. Cell delivery is particularly important in patient popula-
tions where stem cell populations are inactive or
relatively depleted such as the elderly or
diseased.
The detection, isolation, and sorting of cells
hold an important role in cell therapy and regenerative medicine. Custodio et
monoclonal antibodies against cell surface antigens specific to endothelial cells and stem cells
that were immobilized on the surface of the microparticles [24]. They demonstrated the ability of
biofunctionalized particles to select specific cell
types from mixed cell populations and to promote cell expansion, by using human adipose
stem cells (hASCs) and human umbilical vein
endothelial cells (HUVECs) as examples. The
versatility of this method allows the combination
of the biotin conjugated microparticles with any
biotinylated molecule as antibodies, growth factors, or peptides of interest. They showed that
biodegradable and biocompatible particles functionalized with antibodies presented selective
affinity to cells, making them potentially suitable
for separating subpopulations of cells from complex mixtures. Besides the ability for cell separation, the cultured particles proved to be also
suitable for cell expansion. They were able to
develop an in
easy-to-operate system with the capability to
simultaneously separate and expand different
cells subsets. The aggregation of the functionalized microparticles was shown to successfully
form 3D robust structures upon injection into a
mold. Thus, the developed microparticles demonstrated they might be potentially useful for further studies accomplishing the formation of a
construct in situ upon implantation using minimally invasive procedures.
The minimally invasive delivery of bioscaffolds and cells to a variety of tissue-specific
defect poses will need to be addressed prior to
clinical translation. An example of such an
approach is the study by Subhan et
they developed a technique for minimally invasive and accurate delivery of MSCs in a hydrogel
to augment the nucleus pulposus (NP) in damaged intervertebral discs (IVD) [19]. Their
results demonstrated that the minimally invasive
administration of MSCs in hyaluronan hydrogel
vitro versatile, cost-effective, and
al. developed

(HyStem) can successfully augment the repair of
NP in damaged IVD. Ibarra et al. were able to
arthroscopically implant autologous matrixencapsulated chondrocytes in a bioabsorbable
scaffold into the knee for cell-based cartilage
repair. They demonstrated efficacious and reproducible results with a mean of 36 months of follow- up [20]. Leggett and others were able to
utilize gastrointestinal endoscopy to transplant
autologous epidermal cell sheets or seeded
decellularized biological scaffolds to repair
strictures resulting from endoscopic submucosal
resection and circumferential endoscopic mucosal resection. This technique can also be used to
augment the lower esophageal sphincter with the
injection of muscle-derived cells for a novel
potential treatment for gastroesophageal reflux
disease [21].
11.7 Transplantation of Organ
Germs: Salivary Glands
Regenerative tissue engineering techniques have
often drawn inspiration from embryology to
understand and recapitulate the steps involved in
organogenesis. Most organs develop embryologically with reciprocal interactions from at least
two distinct cell layers collectively known as
organ germs. Therefore, there has been an attempt
to bioengineer organ germs for transplantation
that will differentiate and form end organ structures in vivo [22]. Although this technique, pioneered by Takashi Tsuji’s group in Japan, requires
cell harvesting, the transplantation of organ
germs would have minimal surgical morbidity
and therefore may be considered minimally invasive as compared with whole organ transplantation [22].
One potential application for the bioengineered organ germ method is the formation of
salivary glands. Hyposalivation or xerostomia,
frequently associated with a history of head and
neck radiation or autoimmune dysregulation,
can have significant clinical sequela including
tooth decay, impaired mastication, swallowing
dysfunction, and often decreased quality of life.
Current treatment options for xerostomia are
often palliative and insufficient; therefore, the
development of a engineered salivary gland that
responds to gustatory stimulation would have
significant clinical impact. Embryologically
salivary glands develop with reciprocal epithelial and mesenchymal cell interactions resulting in duct and acina formations, which are
the functional unit of salivary glands. Ogawa
et al. demonstrated that a bioengineered salivary gland tissue germ fabricated with isolated
epithelial and mesenchymal cells from mouse
submandibular glands connected with a polygycolic acid monofilament thread guide could be
successfully engrafted in a murine model of
salivary gland defect [23]. The resultant tissue showed morphologic gland formation and
functional amylase positive saliva secretion.
This proof of concept study demonstrates the
utility of bioengineered organ germ development for important clinical problems including
xerostomia.
Conclusions
In situ tissue engineering is a minimally invasive method for the surgical correction of tissue defects or physiologic disease. The
examples discussed in this chapter illustrate
that the implantation of biomaterials with biologic cues can be used to harness the body’s
regenerative capacity through a process of cell
homing of host stem cells from both vascular
and interstitial sources.
