项目摘要
Project Summary/Abstract
Preterm infants are at increased risk of health complications due to their under-developed organ systems at
birth, and human milk receipt is recognized as an important intervention to promote infant health. Recent
identification of cells in human milk which have similar characteristics to stem cells, as well as animal models
which show integration of these cells into nursling's organs, indicate an important function of milk cells which is
currently not understood. In the NICU, infants often receive human milk which has been refrigerated or frozen,
and then warmed and/or thawed prior to feeding. The impact of these typical handling practices on the cellular
components of milk that may provide an important mechanism of biologic protection in infant health has not
been investigated. This work will determine how the real-life storage and handling of human milk impacts infant
health and development, and is the first to evaluate protective mechanisms. There are currently two major
knowledge gaps in the fields of human milk and lactation and neonatal care surrounding bioactive cellular
components. The first is a lack of knowledge of how real-life storage and handling practices impact the
protective ability of milk's cellular components for infants. Without this knowledge, infants who may benefit from
milk with the most bioactivity (such as preterm infants) may not receive the properties of their mother's milk
which provide important protection. The second major opportunity is the lack of knowledge on the
mechanism(s) of protection in milk stem-like cells. Additionally, as research techniques advance our ability to
investigate milk components, there is a great need to look at milk components in a biological systems
perspective. The specific aims of the research project are to 1) examine how hospital storage practices
(refrigeration and freezing) impact the protective mechanisms of human milk cells through the use of a tissue
culture model of intestinal health, and 2) determine if milk cells are integrated as functioning cells specific to
vital organs impacted by preterm birth (brain, heart, lungs, intestine) using a cross-foster mouse model. Upon
completion of the specific aims of the K23 research strategy and training plans, the candidate will have
advanced theoretical knowledge and technical skills to conduct human milk research with the ability to apply a
biological systems approach to understand the complexity of the many components of milk which likely impact
the function of each. The proposal research aims are supported by research training, didactic coursework,
scientific meetings, and specific plans for dissemination and future growth. Ultimately, the short- and long-term
goals of this research are to 1) improve infant health by optimizing the delivery of the most bioactive human
milk components and 2) determine the mechanism(s) by which human milk cells protect infants and promotes
growth and development.
项目总结/摘要
早产儿由于器官系统发育不全,
婴儿出生和母乳喂养被认为是促进婴儿健康的重要干预措施。最近
在人乳中鉴定具有与干细胞相似特征的细胞,以及动物模型
显示这些细胞整合到哺乳动物的器官中,表明乳细胞的重要功能,
目前还不了解。在NICU中,婴儿通常接受冷藏或冷冻的人乳,
然后在喂食前加热和/或解冻。这些典型的处理实践对蜂窝网络的影响
牛奶中可能提供婴儿健康生物保护重要机制的成分,
被调查了这项工作将确定母乳的实际储存和处理如何影响婴儿
它是第一个评估保护机制的机构。目前有两大
母乳、哺乳和新生儿护理领域的知识空白,
件.首先是缺乏对实际存储和处理实践如何影响
牛奶的细胞成分对婴儿的保护能力。如果没有这些知识,婴儿可能会受益于
具有最大生物活性的乳汁(如早产儿)可能得不到其母乳的特性
提供了重要的保护。第二个主要的机会是缺乏知识,
乳干细胞样细胞的保护机制。此外,随着研究技术的发展,
调查牛奶成分,有很大的需要看看牛奶成分在一个生物系统
perspective.该研究项目的具体目标是:1)检查医院存储实践
(冷藏和冷冻)通过使用组织影响母乳细胞的保护机制
肠道健康的培养模型,以及2)确定乳细胞是否被整合为特异于
早产影响的重要器官(脑、心脏、肺、肠)。后
完成K23研究战略和培训计划的具体目标,候选人将有
先进的理论知识和技术技能,进行母乳研究的能力,
生物系统的方法来了解牛奶的许多成分的复杂性,
每个人的功能。该提案的研究目标得到了研究培训,教学课程,
科学会议,以及传播和未来增长的具体计划。最终,短期和长期
这项研究的目标是:1)通过优化最具生物活性的人类
2)确定母乳细胞保护婴儿和促进婴儿发育的机制
促进经济增长和发展。
