Applications of Cell Surface Engineering in Stem Cells

By leveraging the capacity to promote regeneration, stem cell therapies offer enormous hope to overcome diseases that conventional therapy had only limited success. However, because of the insufficient homing and survival of the viable cells with high efficiency to target tissues, the therapeutic efficacy of stem cell therapy is still very low. To address this challenge, scientists have applied cell surface engineering technology to chemically attach cell adhesion molecules to the stem cell surface to improve the homing efficiency of specific tissues.

Importance of Cell Surface Engineering in Stem Cells

Stem cells have various advantages including self-renewal and differentiation ability, autologous source and immune modulator, unlimited source and patient-specific application. However, stem cell therapy shows a very poor efficacy of targeted delivery, retention, and engraftment of injected cells, which still limits the practical applications. Cell surface engineering has developed to be one of the promising solutions to overcome the low therapeutic efficacy of stem cell therapy by introducing artificial active molecules on the cell membrane. It can be applied to various scientific research, including but not limited to:

Cell surface engineering can modulate the cellular behavior to enhance the targeted delivery, cellular functions, organized structure, and immune evasion by chemical or physical modification of the cell surface. Driven to increase the therapeutic efficacy of stem cell therapy, Creative Biolabs is dedicated to offering stem cell surface engineering services that can be tailored to modulate stem cell function and interactions. We have developed an impeccable cell surface engineering platform to provide flexible solutions and various conjugates. Please contact us for more detailed information to know how we can help.
