In a 2012 study,<ref name="Lai, Y 2011">{{cite journal | vauthors = Lai Y, Asthana A, Kisaalita WS | title = Biomarkers for simplifying HTS 3D cell culture platforms for drug discovery: the case for cytokines | journal = Drug Discovery Today | volume = 16 | issue = 7–8 | pages = 293–97 | date = April 2011 | pmid = 21277382 | doi = 10.1016/j.drudis.2011.01.009 }}</ref> Koch et al. focused on whether Laser-assisted BioPrinting (LaBP) can be used to build multicellular 3D patterns in natural matrix, and whether the generated constructs are functioning and forming tissue. LaBP arranges small volumes of living cell suspensions in set high-resolution patterns.<ref name="Lai, Y 2011"/> The investigation was successful, the researchers foresee that "generated tissue constructs might be used for [[in vivo]] testing by implanting them into [[animal models]]" (14). As of this study, only human skin tissue has been synthesized, though researchers project that "by integrating further cell types (e.g. [[melanocytes]], [[Schwann cells]], hair follicle cells) into the printed cell construct, the behavior of these cells in a 3D in vitro [[Microenvironment (biology)|microenvironment]] similar to their natural one can be analyzed", which is useful for drug discovery and [[toxicology]] studies.<ref name="Lai, Y 2011"/>
