Dental Pulp Stem Cells – the big needle vs the tooth fairy

Little Jane asks “Daddy, where will they get the stem cells to make me better?”

Daddy’s answer now “They will get some from your bone marrow.  They stick in a big needle to get it.”

Previous posts on this blog have discussed applications of adult stem cells for tissue regeneration, for example the recent post Simple but powerful non-invasive adult stem cell cures.  Many of these feature the use of autologous mesenchymal stem/progenitor cells extracted from a patient’s own bone marrow.  Mesenchymal stem/progenitor cells are an important category of stem cells which self-renew and are capable of differentiating into bone, adipose and cartilage tissue.  Traditionally these cells have been extracted from bone marrow although they have been known to exist also in placenta, lung and other tissues.  Recently there has been increasing interest in Dental Pulp Stem Cells (DPSCs) for dental tissue restoration, including regeneration of dental pulp and dentine(ref)(ref)(ref)(ref). 

Beyond dental applications, there may be a number of other applications of DPSCs for repair or regeneration of other body tissues.  DPSCs appear to be functionally equivalent to mesenchymal stem/progenitor cells, are relatively easy to collect, have an extensive differentiation capability and offer several other advantages(ref)(ref).  DPSCs “have been demonstrated to answer all of these issues: access to the collection site of these cells is easy and produces very low morbidity; extraction of stem cells from pulp tissue is highly efficiency; they have an extensive differentiation ability; and the demonstrated interactivity with biomaterials makes them ideal for tissue reconstruction. SBP-DPSCs are a multipotent stem cell subpopulation of DPSCs which are able to differentiate into osteoblasts, synthesizing 3D woven bone tissue chips in vitro and that are capable to synergically differentiate into osteoblasts and endotheliocytes. Several studied have been performed on DPSCs and they mainly found that these cells are multipotent stromal cells that can be safety cryopreserved, used with several scaffolds, that can extensively proliferate, have a long lifespan and build in vivo an adult bone with Havers channels and an appropriate vascularization(ref).”  In other words, for many tissue repair and regeneration applications DPSCs might offer a better choice that bone-marrow extracted mesenchymal stem cells.  And there are likely to be a lot of such applications.

In the future little Jane asks: “Daddy, where will they get the stem cells to make me better?”

Daddy’s answer:  “The tooth fairy collects it.  Just leave your baby tooth under your pillow when it comes out.”

About Vince Giuliano

Being a follower, connoisseur, and interpreter of longevity research is my latest career, since 2007. I believe I am unique among the researchers and writers in the aging sciences community in one critical respect. That is, I personally practice the anti-aging interventions that I preach and that has kept me healthy, young, active and highly involved at my age, now 93. I am as productive as I was at age 45. I don’t know of anybody else active in that community in my age bracket. In particular, I have focused on the importance of controlling chronic inflammation for healthy aging, and have written a number of articles on that subject in this blog. In 2014, I created a dietary supplement to further this objective. In 2019, two family colleagues and I started up Synergy Bioherbals, a dietary supplement company that is now selling this product. In earlier reincarnations of my career. I was Founding Dean of a graduate school and a full University Professor at the State University of New York, a senior consultant working in a variety of fields at Arthur D. Little, Inc., Chief Scientist and C00 of Mirror Systems, a software company, and an international Internet consultant. I got off the ground with one of the earliest PhD's from Harvard in a field later to become known as computer science. Because there was no academic field of computer science at the time, to get through I had to qualify myself in hard sciences, so my studies focused heavily on quantum physics. In various ways I contributed to the Computer Revolution starting in the 1950s and the Internet Revolution starting in the late 1980s. I am now engaged in doing the same for The Longevity Revolution. I have published something like 200 books and papers as well as over 430 substantive.entries in this blog, and have enjoyed various periods of notoriety. If you do a Google search on Vincent E. Giuliano, most if not all of the entries on the first few pages that come up will be ones relating to me. I have a general writings site at and an extensive site of my art at Please note that I have recently changed my mailbox to
