Synthetic biology and engineered tissue patterning

Leduc defined synthetic biology as the synthesis of the constituents, forms and functions of living things.1 Leduc used the term in 1911 for work on form made by diffusion.2 Davies and Glykofrydis describe the modern version, in which cells are engineered to pattern and shape themselves, as a test of developmental understanding and a base for tissue engineering.67

01

Leduc's synthetic biology

Leduc (1911), in The Mechanism of Life, counted synthetic biology as three branches: synthetic organic chemistry, morphogeny and physiogeny.1 Morphogeny was the synthesis of living forms and structures. Physiogeny was the synthesis of functions.1 He judged that chemistry was already a well-organized science, while the other two could hardly yet be said to exist as sciences.1 He described the field as the final one in the evolution of biological science, opened by progress in physico-chemical science.2 His own results used the diffusion of liquids to obtain forms that imitated cellular tissues, and also striated structures such as muscle and mother-of-pearl.2

Tissue engineering meets circuits

Davies and Cachat (2016) argued that classical tissue engineering will continue as synthetic biology develops towards being useful to it. They thought most of its current priorities, which centre on normal tissues, might be reached without a synthetic input.3 They said synthetic approaches may make the task easier. They also noted that many printing processes in bioprinting, one of the most promising techniques, place serious stresses on cells.3 They added that synthetic biologists from the prokaryotic world might find mammalian systems frustrating. Natural cell-cell interactions stay active unless the synthetic system blocks them.4 Kamm and colleagues (2018) wrote that engineered multicellular living systems need many disciplines, and named convergence as key.5

03

Engineered patterning and morphogenesis

Davies and Glykofrydis (2020) reviewed mammalian systems built so far. They covered patterning systems, both contact-mediated and reaction-diffusion, and the effectors of morphogenesis. They also covered early attempts to join the two into self-organizing physical form.6 They argued that engineering autonomous pattern formation tests axiomatic understanding of developmental biology and lays a foundation for advanced tissue engineering.7 Pio-Lopez, Hartl and Levin (2025) cite multiscale competency as a framework for synthetic biology and regenerative medicine.8 Chen and colleagues (2025) discuss piezoelectric scaffolds for stem cell adhesion and migration in tissue engineering.9

Linked ideas
Synthetic living machinespart of / contains
Engineering form directly is the shared aim, from Leduc's morphogeny to the engineered patterning systems reviewed by Davies and Glykofrydis.
Reaction-diffusion is one of the two patterning modes, with contact-mediated patterning, that Davies and Glykofrydis describe in engineered mammalian cells.
Engineered living constructs of this kind are among the multicellular systems that the synthetic and tissue-engineering literature aims to build.
Designing living systems by computation sits close to the goal of engineering pattern and form from cells.
Both treat building living systems as a way to learn what living systems can be, as Leduc argued for synthesis.
Regenerationrelated to
Regenerative medicine is named alongside synthetic biology as a field that multiscale competency could inform.
Evolvabilityrelated to
Passages say synthetic biology and chimeric engineering blur evolved versus designed systems, and Davies lists evolvability and robustness as pattern-engineering goals; no passage directly links evolvability theory to tissue patterning.
Basal cognitionrelated to
Passages treat synthetic biology as a platform for basal cognition: engineered constructs (biobots, gap-junction circuits) enable testing memory, learning and goal-directed morphogenesis in non-neural systems; they overlap without one containing the other.
Law & Levin identify ion channels as a synthetic-biology toolbox for rewritable bioelectric voltage memories; Chen et al. link bioelectric cues to stem-cell adhesion. Passages don't directly equate the two topics.
Davies and Cachat place the modules within a developmental cycle for building tissues.
