Cell Therapy
CellTherapy or Cytotherapy is the transfer of cells into a patient with a goal ofimproving the disease. From beginning blood transfusions were consideredto be the first type of celltherapy to be practiced as routine. Later, Bone marrow transplantation hasalso become a well-established concept which involves treatment of much kind ofblood disorders including anemia, leukemia, lymphoma and rareimmunodeficiencydiseases. Alternativemedical practitioners perform celltherapy in the form of several different names including xeno-transplanttherapy, glandular therapy, and fresh celltherapy. It has been claimed by the proponents of celltherapy that it has been used successfully to repair spinal cord injuries,strengthen weaken immune system, treatsautoimmunediseaseslike AIDS, helppatients with neurological disorders like Alzheimers disease, Parkinsons diseaseand epilepsy.
GeneTherapy
GeneTherapy basically involves the introduction or alteration of geneticmaterial within a cell or organism with an intention of curing the disease.Both celltherapy and gene therapy are overlapping fields of biomedical research withthe goals of repairing the direct cause ofGeneticdiseasesin DNA orcellular population respectively, the discovery of recombinant DNA technologyin the 1970s provided tools to efficiently develop genetherapy. Scientists use these techniques to readily manipulate viralgenomes, isolate genes and identify mutations involved in human disease,characterize and regulategeneexpressions, and engineer variousviral and non-viral vectors. Various long-term treatments for anemia,hemophilia, cystic fibrosis, muscular dystrophy, Gauschers disease, lysosomalstorage diseases, cardiovascular diseases, diabetes and diseases of bones andjoints are resolved through successful gene therapy and are elusivetoday.
StemCell Therapies
CellTherapy is defined as the therapy in which cellular material is injectedinto a patient in order to recover the healthy tissue. Celltherapy is targeted at many clinical indications in multiple organs bymeans of several modes of cell delivery.Stem-CellTherapyis the use ofstem cells to treat or prevent a disease or condition. Stemcells are a class of undifferentiated cells which are able to differentiateinto required or specialized cell types. Adult or somatic stem cells exist throughout the body after embryonic development and arefound available inside the different types of tissue. The stem cell methodologyincludes the phases of Stem cell or progenitor cell engraftment,differentiation followed by long term replacement of damaged tissue.
CellCulture and Bioprocessing
A Stem-Cell line is a group of undifferentiated stem cells which is culturedinvitro and can be propagated indefinitely. While stem cells can propagateindefinitely in culture due to their inherent cellular properties, immortalizedcells would not normally divide indefinitely but have gained this ability tosustain due to mutation. The Immortalized cell lines can be generated from cells by means of isolating cells fromtumors or induce mutations to make the cells immortal. An immortalizedcell line is a population of multicellular organism cells which has notproliferates indefinitely. Due to mutation, the cells evaded normal cellularsenescence and instead undergoing continuous celldivision. A key factor in reducing the production costs ofbiopharmaceuticals is the development of cell lines which in turn produce ahigh yield of product.
TissueScience & Regenerative Medicine
Regenerative Medicine is the branch of translational research deals with the processof replacing, engineering or regenerating human cells, tissues or organs inorder to restore or establish normal functionality of cell. Regenerativemedicine is the combination oftissueengineeringand Molecular Biology. CellTherapy mediate cell repair via five primary mechanisms: providing ananti-inflammatory effect, homing to damaged tissues and recruiting other cellssuch as endothelial progenitor cells for necessary tissue growth, supportingtissue remodeling over scar formation and inhibiting apoptosis programmablecell death and differentiating tissues into bone, cartilage, tendon andligament tissue.
ClinicalTrials on Cell & Gene Therapy
Clinical Trials of Celland Gene Therapy products often varying from the clinical trials design for other types of pharmaceutical products. Thesedifferences in trial design are necessitated by the distinctive features ofthese products. The clinical trials also reflect previous clinical experienceand evidence of medicine. Early experiences with Cell and Gene Therapy products indicate that some CGT products may posesubstantial risks to subjects due to effect at cellular and genetic level. Thedesign of early-phase clinical trials of Cell and Gene Therapy products ofteninvolves the following consideration of clinical safety issues, preclinicalissues and chemistry, manufacturing and controls (CMC) issues that areencountered.
NanoTherapy
Diseases can betreated using viruses as vector to deliver genes inGeneTherapy. Viruses as genevector however, can themselves cause problems in that they may initiateinflammation and the genes may be expressed at too high a level or for too longperiod of exposure. The goal of Nano Technology in genetherapy is delivery of therapeutic genes without a virus, usingnanoparticles as non-viral vector to deliver the genes. The particles canbe made with multiple layers so the outer layer with covering of peptide thatcan target the particles to cells of interest at specific site. The emergent Nanotechnologyin gene therapy is used to develop unique approaches in treating theretinopathies and the development of micro and Nano dimensional artificialantigen presenting cells forcancerimmunotherapy. These antigenpresenting cells mimic the natural signals in immunity that killer T-cellsreceive when there is an invader (bacteria, virus, cancer cell, etc.) in thebody.
AdvancedGene Therapeutics
Functionality ofbiomaterials for these forms is depends upon the chemical reaction such aslocalized or systemic response at the surface tethered moieties or encapsulatedtherapeutic factors such as drugs, genes, cells, growth factors, hormones andother active agents to specific target sites. The application of functional biomaterials is rehabilitation, reconstruction, regeneration, repair,ophthalmic applications and act as therapeutic solutions. It has the propertyof biocompatibility and produce inertness response to the tissue.Thebiomaterial-mediated gene therapy aim to use polymeric gene therapy systems tohalt the progression of neuron loss throughneuroprotectiveroutesand it combine stemcell therapy and biomaterial delivery system in order to enhance regeneration or repairafter ischemic injury.
Geneand Cell Therapy for Rare & Common Diseases
Gene therapy is a superior method to treat uncommon hereditary maladies; fixa solitary quality deformity by presenting a 'right' quality. The main qualitytreatment preliminaries were directed utilizing patients with uncommonmonogenetic issue, however these are presently dwarfed by the clinical testingof quality therapeutics for more typical conditions, for example, malignancy,AIDS and cardiovascular illness. This is halfway because of an inability toaccomplish long haul quality articulation with early vector frameworks, a basicprerequisite for amending numerous innate hereditary deformities. Presently, with the appearance ofadeno-relatedviral(AAV) and lent viral vectors, which show steady qualityarticulation in creature thinks about, this mechanical obstruction, may havebeen survived. These vectors are foreseen to shape the premise of numerous genetherapy protocols for acquired hereditary illnesses.
CellScience and Stem Cell Research
The extract derivedfrom the plant cell culture technology is being harnessed and utilized as anactive ingredient in anti-aging skincare products. In recent years, researchershave identified naturally occurring botanicals with substantial antioxidantactivity proven to protect skin stem cells from UV-induced oxidative stress,inhibit inflammation, neutralize free radicals and reverse the effects ofphoto-aging by means ofanti-oxidantactivity. Consequently,cosmeceutical products containing plant stem cell derived extracts have theability to promote healthy cell proliferation and protect against UV-induced dermatological cellular damage in humans. In contrast to epidermal stem cells,plant stem cells are totipotent that they are capable of regenerating anentirely new, whole plant. Through innovative plant stem cell technology,scientists are able to extract tissue from botanicals and regenerate stem cells can be harnessed for use in humans. The use of stem cellsderived from botanicals plant, rather than human stem cells, avoids thecontroversy surrounding the source or methods of extraction of human stem cellswhile still harnessing the potential of these intriguing cells and its effectin anti-photo aging.
