Humans lack substantial regenerative capabilities, many non-human species, such as amphibians and certain fish, can repair, regenerate and remodel substantial portions of even their brain and brain stem even after a critical life-threatening trauma.
Cell-based therapy has emerged as a promising approach to and enables the fabrication of functional tissues or organs that could be used for reparative procedures in patients. However, this approach requires a donor tissue and extensive cell expansion steps before Implantation for therapy. Moreover, isolated tissue-derived primary cells are often heterogeneous and difficult to standardize. Thus, obtaining a reliable and reproducible cell source has been one of the challenging elements of cell-based approaches.
This has motivated the development of a new strategy that eliminates the ex vivo cell manipulation before implantation, and this approach would decrease the time, effort, and resources required to generate a tissue/organ substitute.
Recent progress in regenerative medicine has adopted the concept of utilizing endogenous cells for in situ tissue regeneration. The principle of in situ tissue regeneration is to utilize the body’s own biologic resources and its reparative capability by using a target-specific Bioactive Molecules to recruit host stem or tissue-specific progenitor cells to the site of injury.

This novel approach would allow for damaged tissue to be regenerated without the need for cell transplantation .these bioactive molecules unlock the body’s own regenerative capability.
In turn, this induces the mobilization of tissue-specific host stem/ progenitor cells, drives proliferation, and differentiation of these recruited cells into the targeted cell types and regenerates functional tissues.
Extensive study over the last century has shed a substantial amount of knowledge on the processes of intercalary regeneration and the unique and multi-mechanistic dynamics that are involved in re-starting a defined generative developmental pattern to specifically fill in missing or damaged tissues and organism a living organism.
These soluble factors get into the regulatory architecture of cells and support both reprogramming and early remodeling bio-activities of the new genome. Independently these factors do very little, but in the right synergy MOA arises – this is the stochastic way epimorphic regeneration/repair events naturally occur in tissues. Reprogramming of cells in target tissues to a multi/pluripotent progenitor state.

- A key to in situ tissue regeneration in the initial stage is proficient recruitment of host stem or progenitor cells, adult stem cell populations in the body are generally too low in number to have a significant impact on accelerated tissue regeneration. Therefore it is worthwhile to target these cells to be effectively mobilized into the peripheral blood system from bone marrow adipose tissue and other reservoirs.
- Bioactive molecules that induce engraftment of the mobilized host stem cells into Desired tissues or organs for repair are considered as important Cues for efficient in situ tissue regeneration.
- Differentiation into the desired tissue type. Induction of the infiltrating cells into tissue-specific cell lineages for functional tissue regeneration.
- Signal the endogenous stem cells for growth and differentiation. Bioactive molecules play an important role in guiding host cells to form a well-integrated functional structure. Most adult stem cells are quiescent and reside in a specialized microenvironment, which is called a ‘stem cell niche’. In response to regulatory signals that originate from tissue injury, these stem cells become activated and begin the repairing process. Bioactive molecules and biophysical cues that enhance cell migration, proliferation, and differentiation to produce a biofunctional host stem cell niche.
- Modulate inflammatory response Peptides would help in the innate immune response. An appropriate level of activation of the regenerative side of the innate immune response (versus the adaptive immune response) to support morphogenesis
- Mimic the regulatory characteristics of natural extracellular matrices (ECMs) and ECM-bound growth factors, both for therapeutic applications and basic biological studies.
- Present bioactive ligands and respond to cell-secreted signals to enable proteolytic remodeling. An appropriate histolytic response for extracellular matrix remodeling in targeted tissues,
- These materials have already found application in differentiating stem cells into neurons, repairing bone, and inducing angiogenesis.
- Contain the necessary signals to recapitulate developmental processes in tissue- and organ-specific differentiation and morphogenesis
Based on the last several decades of extensive in-vivo work using human embryonic cells certain protein molecules have been identified which have a very high capacity to reprogram, regenerate and repair any type of cell including neural, hepatic, and renal, etc.
Peptides and m RNAs: The solution contains highly active protein molecules and with mRNAs. They have a very high capacity to reprogram, regenerate, and repair any cell type. They are highly effective on many cell types including neural, hepatic, renal, skin, etc.
General growth factors: These are a purified mixture of growth factors that help in increasing stem cells in the general circulation thus increasing the regenerative capacity of the complete body. They also increase the survival of implanted/injected stem cells.
Neural growth factor: These are specialized growth factors that help in homing of the stem cells in damaged //diseased neural tissue. It also helps stem cells to differentiate into neurons. It also stimulates the endogenous neural stem cells.
For neurological indication, intralesional /intrathecal and IM use of bioactive peptides and subcutaneous neural growth factors will be the best. For muscle and cartilage intraarticular. For other Indications IM application and Bioactive peptides and Subcutaneous administration of Genotrop.
