Genetic engineering cells

Whole cell silicate sensors14 will soon make use of the viability of cells and their ability to respond to external conditions, using genetically engineered cells tailored to emit measurable optical or electrical signals. The operation principle is shown in Figure 6.15. 

The same pharmacokinetic limitation is true in principle for the implantation of encapsulated genetically engineered cells, which synthesize and release neurotrophic factors [68]. 

Pioneering studies have demonstrated the potential of gene therapy for the treatment of inherited hematopoietic diseases [440300], and particularly for ADA-SCID [470017], [470024], [666662], [666664], [666665]. However, vector design, gene transfer protocols and inadequate engraftment and expansion of genetically engineered cells limited the success of earlier studies [206054], [657269], [657273], [668669]. 

Whole cells (for example, primary hepatocytes or genetically engineered cells) provide the simplest intact system for the study of xenobiotic metabolism (Ratanasavanh et al., 1986 Daujat et al., 1991 Berry et al.,... 

Whole cells have substantial advantages in applications to toxicology. However, many primary cells have a limited life span, and do not replicate in culture. This limits toxicology applications to short-term studies. Genetically engineered cells overcome this limitation. They represent a stable dividing population which permits longer-term studies. 

The surviving genetically engineered cells are regenerated into whole plants. 

A month later, I arrive early at the lab and hurry over to the growth chamber to check on my tiny plants. Hurrah The genetically engineered cells have produced shoots and roots, the result I was anticipating. I carefully transplant the GE seedlings into soil-filled pots.
